The Story:
So I just upgraded my relic PowerMac G5 tower to one of the brand new 27-inch iMacs. My Captivate refuses to mount when plugged into any USB port on the back of the iMac. Yes, USB debugging is on. Yes, I pushed the button to mount the phone. The computer just refused to recognize it. The phone DID, however, start charging immediately. So it was pulling power, but not mounting at all.
Only major differences I could think of were the processor (G5 PowerPc to Intel Core i7), OS (Leopard to Snow Leopard), and that I'm using FileVault this time around. I did some searches to see if there were any known issues, but couldn't find any since the new iMacs came out a few weeks ago.
I know Adam Outler has been using his Captivate with Snow Leopard, so I tried turning off File Vault. Made no difference. I also tried plugging in my Nikon D3100 and my old iPod classic into the computer. The camera did not mount, but the iPod did. Luckily, the camera has a HDSD card, which plugs directly into the iMac. But I still couldn't get the phone to connect.
Just for a laugh, I plugged the phone into my ancient USB 1.0 hub. Damn thing mounted right up. WTF? I know USB 1 isn't going to cut it speedwise, so I got a USB 2.0 hub and tried it. Again, mounted like a champ. Ran adb reboot recovery from Windows (through Parallels), and it worked.
Turns out the camera just doesn't mount for any Macs (might explain why it didn't come with a USB cable). But the phone is still a mystery.
Question 1: Is this a power thing? Could it even be possible that my Captivate needs more power to mount than my iPod Classic (which has a hard drive, not flash memory)?
Question 2: Does anyone have any idea why this occurs? Is there some setting that I don't know about that controls what mounts and what doesn't?
Thanks for any thoughts on this,
kk
do u have the captivate drivers??? my mac hooks up my captivate all the time... i have teh 21 inch model tho not the 27 but yea drivers, usb debugging and device set to mass storage...
There are no drivers for Mac. I do have the proper drivers for PC (through parallels).
Yes, I have the phone set to both Mass Storage and USB debugging.
The weird thing is that I can mount the phone if I plug it into the USB hub...but NOT the USB ports ON the computer itself. If I plug in the phone to the computer directly and select Mount, neither the Mac nor PC side see it.
The trouble with the hub (USB 2) is it's SLOOOOWWWWW. I tried to copy my Titanium Backup folder to the Mac through the hub and it copies really slow then keeps cancelling out. Right now I'm transferring it via Bluetooth...and it's painfully freaking slow, too.
Anyone else have this problem? It's one of the brand new iMacs just released in May. It's killing me.
[solved] New iMac Weirdness
Figured it out.
Believe it or not, it's the cable (yes, the Samsung cable that came with the phone). I used the Motorola cable for my wife's Bravo and the computer recognized the phone right away.
My Samsung cable worked just fine with my G5 tower, but not the new iMac. I'm still wildly perplexed why it would mount through the 7-port USB hub, but not the computer itself.
Doesn't matter now, though. The Motorola cable works just fine.
I've been showing off the Nexus Media Importer, also using for practical purposes. Got a right-angle OTG cable off Amazon, paid too much, but it worked perfect with the mini-16gb flash drive in it. It also work with a card reader no problem. This was rooted on 4.2 using NMI 3.2.2. No problems, great program.
Then I saw there was an update to NMI 4.0. Installed it and now NONE of my USB devices show up. Always says "No Device. Click Scan to Retry". It used to just pop up automatically when I plugged it in. No longer.
I downloaded USB Device Info.
On the Android side, nothing shows up. On the Linux side, usb1 shows up, looks like the internal USB hub. Oddly enough when I plug my OTG USB cable in, a usb2 also shows up on the linux side. All output is identical except for the device where it said usb1 for the usb1 device, it shows usb2. So there's SOME data communication taking place it seems.
I've rebooted, I've discharged and recharged, I've made sure everything is plugged in tight. I am on 4.2 rooted, and have been since before I even installed NMI 3.2.2. The developer is helping but he seems to be in head-scratching mode right now. So, anyone got ideas? This was no the el-cheapo $0.80 USB OTG cable from Hong Kong, I paid quite a bit to get it from Amazon. That said it probably is the exact same cable but I digress. On the off chance that the cable suddenly died the moment I updated NMI, I've ordered another cable (this time a cheap one, but still the right angle).
Please anyone have help? I need this program to work!
Edit: FWIW I saw that Stickmount got updated to support 4.2. Downloaded and installed it. It also doesn't see my flash drive (which was working fine 2 nights ago). Did my OTG just die or did something screw up my devices? I hate to do a hard reset and go through and reconfigure everything, even with TiBu backups.)
I know this doesn't help you, but FWIW, NMI 4 is working fine now 4.2 for me, so it is definitely something on your end.
Do Windows machines see the usb drives ok?
Do you have another device to test the OTG cable with on your phone like a game pad or a Canon DSLR?
I'd suspect the OTG cable...
Windows sees the drive and the card reader just fine, the two devices that were working. I got a new OTG on the way, even though this was brand new, and no, I I don't have any other device to test it on. Also I tried stickMont since its supposedly 4.2 friendly now and It doesn't see anything either. If the new otg doesn't work guess I'll back everything up and factory reset.
Edit: Actually a factory reset will only clear the data - won't reset the system device files will it? I'll need to get a full 4.2 image and put it on, I guess with Wug's, it's what I used before, then re-root, and restore everything with Titanium Backup. Man I hope it's just the cable. It was only 3 days old tho!
Bad cable! Got a new cable and it's fine.

I decided to make this a separate thread apart from the general questions post mainly for anyone who has a similar issue, it will be much easier to follow and ask questions, as well as update it myself when I have more data.
So to begin, I wiped my Touchpad with TPtoolbox v.40, installed CM11 4.4.4 with standard gapps and philz recovery. Everything was working great and going smooth until I tried to use a USB Logitech G11 keyboard and a wireless G700 mouse with the dongle attached to the keyboard. The touchpad will recognize the first device installed to the OTG cable but nothing else I plug into it unless the first device is removed. Let me give some examples of things I have tried.
----OTG Y cable (1 male Micro USB, 1 Female Micro USB power input, 1 Female USB) powered by PC or AC Power supply----
-TP>OTG>Keyboard>Mouse dongle = Keyboard input only
-TP>OTG>Non powered USB hub>Keyboard + Mouse = input based on first device plugged in, if both are plugged in when I plug in the hub, they keyboard always loads first but the mouse does work when keyboard is removed.
-TP>OTG>Non powered USB hub> Keyboard + wireless mini keyboard/mouse combo (Rii i8) + USB flash drive = Everything works, I can type with both the USB keyboard and the mini keyboard with functional mini mouse pad as well as access USB storage. However, when I add any type of dedicated mouse, be it my G700 or wired usb G500, neither work unless I remove the other two input devices.
Cont...
Continued from First Post
Notes: The OTG cable itself works fine using several devices, whether it be flash drives, external hdd, keyboards including a Rii i8 wireless keyboard/mouse combo (touch pad feature works as a mouse with the keyboard, probably because its considered one device.) but I cannot get it to work with a dedicated mouse in conjunction with a keyboard. If I remove the keyboard, again the mouse works fine on its own. If I have the mouse plugged in first, the mouse will work fine but the keyboard will not.
Some of you might be asking, why use a dedicated mouse if I can get the mouse pad on my mini keyboard to work? Gaming
Why not use a Bluetooth keyboard? I do not wish to purchase one and I enjoy my current keyboard
Does anyone have any ideas or a solution? Its driving me insane and I really want it to work with what I have. I even tried making a DIY OTG cable, same results haha.
Update 1: I know this combination works on other devices including Galaxy S3/4/5, and a POS tablet (Envizien or some crap), it really is slow haha but perfect for web and youtube. I figured if this same setup works on all these devices, why not my Touchpad... and here I am lol. Both mouse and keyboard are HID devices so it shouldn't be a problem. I know it has something to do with the touchpad itself, be it a settings and software hack, or I simply need to try a few different roms. I know the touchpad is capable of it, I have seen videos of it being done with what I have. That is what leads me to believe it may be ROM/kernel related.
Update 2: while creating the thread: I wiped the TP again using TPtoolbox v.41 and installed Shumash's Pacman ROM 4.4.4 hoping it was ROM related. No luck. I have attached an image that the TP does indeed recognize the keyboard if I plug it in after the Mouse but I am unable to type anything. I have set the language and default layout to be sure it didn't need to be set, again with no change. I will try an older ROM next to see if it will help.
Thanks again, cheers!

Help please
Tried 6 ROMs total with no luck.
4.3.1: Evervolv
4.4.2: Evervolv
4.4.4: CM11, EOS AIO, and 2 Pac man builds
Same symptoms with each.
Is anyone here with an HP Touchpad currently able to simultaneously use a keyboard and Mouse, wired or wireless through OTG?
Quick update: while running EV 4.3.1, I tried to test it again while at work and when I plugged the Mouse dongle into the USB hub, the mouse showed up but then wouldn't let me move it. I ordered a different OTG and USB Y Cable to better replicate what someone else was using in a youtube video. I just cant see how it works on every other device but this one though.
I really have no idea what to try next so i'm at a standstill.

My work Pc allows me to do basically nothing but visit and post on XDA, is there a way to get the log file through the tp using terminal emulator or another means through the pc without ADB?
Thanks BTW.
Edit: was able to use Terminal Emulator and will email it to myself and upload soon. I hope its what you were looking for haha.
OK attached is the dmesg using last attempted ROM, ev_tenderloin 4.4.2

I intend to go back to your CM11 build, as It seemed to be the smoothest and most reliable of those I tried so far. Im guessing when I do, the kernel will change so my attachment may be useless, i'm not sure. Can't do it here at work though, no Novacom for TPToolbox and the SD card partition is tiny if I were to try and do it using recovery.
New Log, no fix yet.
OK, I am back on cm-11-20141125-SNAPSHOT-jcsullins-tenderloin , attached is the kernel log.

Did you plug in the keyboard and mouse before getting the log?
From that log, it doesn't look like you plugged in any OTG devices.

My apologies, I did not.
Added a second log:
dmesg = TP>OTG Ycable using PC usb power>Keyboard with mouse dongle plugged into the keyboard
dmesg2 = TP> OTG Y cable using AC power adapter> Unpowered USB hub> Keyboard and mouse dongle
Tried the new OTG and Y Cable seen in video that had it working. Didn't make a difference, I am guessing something is wrong with my Kernel like you mentioned. Find anything in my log that I can try and fix? @jcsullins
Thanks

I did not intend to suggest there was something wrong with the kernel.
I think the problem is you are trying to use an un-powered (or bus-powered) USB hub.
Use a (self)-powered USB hub instead.

I misunderstood, my apologies. I will look around at buying a powered USB hub. Can't seem to find any less than $20 with decent reviews, that's in Bluetooth keyboard realm.. I will look at both options I suppose. Thanks again.
Edit: I was just thinking, I had the BUS powered USB hub working with several devices at once, including the wireless mini keyboard, usb keyboard, and a USB flash drive. Wouldn't that be an indication that an Externally powered USB hub is not required? I find it strange that I can get everything to work fine except when it comes to using both a mouse and keyboard at the same time.
Hi everyone
here I've got a terrible issue with my note 8 and SAMSUNG USB OTG.
When I connect my otg and a flash memory to phone, nothing happens, unless you force restart the phone while the otg is connected. After booting I can access to my flash memory but after removing the otg and reconnecting it, again nothing happens unless force restarting.
I've tried everything possible. Downgrading, upgrading, 4 files rom, pit file, rom from different zones, but still have the problem. I have no other issues regarding the USB port and charging, fast charging, connection to computer and any other stuff works fun but this OTG.
I wanted to know if anyone have any solutions for my problem or if anyone had the same issue or not.
it is also worth to mention that I have not rooted my phone due to warranty issues, and for that I haven't tested any kernels.
thanks for everyone

That isn't right... As soon as I plug in my OTG USB key it detects it, no restart required.

allow file transfer .... possible
Nope, I have developer options enabled but debugging isn't on. never had to enable file transfer.
When I plug in the OTG device I see a usb icon in the notification panel. Swipe down and pick explore. Mind you it only opens in the stock file explorer, I did have another file explorer that picked it up too but can't think what it is and it has been lost myriad of other apps I test and play with...
Just be aware that it may take a few seconds to scan the device,depending on size, and then display the icon.

i know it sounds weird but from past experience flaky USB drives are more trouble than they are worth, from first hand experience i know patriot, corsair and sandisk work well as OTG drive
also you neglected to mention the file system the USB was formatted with, i believe only FAT, FAT32 and exFAT are supported

also possible that the phone doesn't like your OTG adapter. I bought a usb 2.0 to type C adapter which doesn't even work on the phone - when I plug it in usually the moisture sensor error comes up saying water is in the device and I should let it dry. Unplug the OTG and the error goes away.
So... I bought a USB 3.0 A to type C OTG adapter and that one works fine with everything I've tested (usb flash drives, keyboard, usb ethernet adapter, etc)
I believe the USB-C to USB-A adapter that came with the phone is actually an OTG adapter (tested xbox360 controller and keyboard)
I also believe that the note8 can host usb flash drive native (no need for OTG cable) as i have a dual head USB-C and USB-A flash drive which is recognized once the USB-C end is plugged in

Sorry to dredge up a semi old thread, but has anyone found a fix for this?
I'm having almost the same issue, I finally decided to try out the OTG adapter from the box and nothing works, it isn't even recognized. Tried ps4 controller, mouse, keyboard 2 different thumb drives. Can't figure out what the deals is.
Other than that pc connection seems to work and charging works fine. TIA
I'm having a similar problem. A month ago, used both OTG adapters (original from Samsung and a generic one) it detects my memory sticks as a hard-disk and was able to manage my files. But since a couple of weeks ago it does not detect them anymore. Is like it did not supply charger to them anymore. I have tried the USB debugging menu and no difference at all. Even I got back to factory reset expecting to solve the issues but nothing happened. The port as such is working perfectly because I'm able to charge through it. On the other hand, Samsung DEX is not working as well. It just charges the phone but never boot-up.
I'm just waiting for Oreo and hopes this will sort the problems out.

Seems to be a little bit dusty. Anyway, the other thing is that, when the Usb is detected it ask to choose between transfer files, images, midi device and so on, even if I choose "transfer files" mode it always get stuck as "charge connected device".
Hi i have the same problem... my note 8 can connected mith my notebook, but my otg with an usb stick cant recognize my note8. I test the same otg with usb stick on my friends phone example S8 and it detects promptly all.
I hope the fixing take not long time. I waiting for help. Greets
Well, adding one more case here, my native file manager doesn't recognize any memory connected via the original otg conector, but, using x-plore file manager, problem solved, as I use x-plore since my symbian days, I never gave this issue much importance, this problem was present also with my note 7

This. I have exactly the same experience. I bought a couple of months ago a new Note 8, and finally decided to try the OTG adapter that came in the box. Nothing worked. I tried the adapter with a friends phone and it worked like magic (USB drives, mice, keyboards, controllers, etc.).
Would really apreaciate if anyone can provide help on this issue... Cheers!
So the story is that i got a samsung galaxy note 5 (n920i) with a broken screen from my sister and it worked fine before. A year later i fixed the phone and wiped the files, cache and stuff i noticed that it did not charge with my aftermarket charging cable (battery was at 0%). I thought the cable was screwed so i used an official samsung one and it started charging. once it started up i did all the startup installation process and such but then i noticed that it would not use fast charge (i have an official samsung fast charge socket) even with the fast charge setting on. so i thought to plug it into my pc but it does not recognise it at all. (device descriptor request failed every time) I used many different ports on my pc and laptop, used many aftermarket and official charging cables, i even used it on devices like the gear vr and a docking station and they dont recognise it either.
I found a post saying to push up the tongue in the charging port which did not fix it, i tried all such drivers and fixes thinking its my pc and/or laptop but no luck, like i said i even used devices like docking station and gear vr and both dont recognise it either. So i just thought it may be the charging port its self and purchased a new one to install(i also got a new battery just incase) . After replacing both the charging dock and the battery successfully it still does not work on my pc nor does it charge properly. it is running on the newest update out right now.
edit: I also lost the little white signal cable for the antenna while replacing charge port but i have purchased a new one and its on the way. (if that causes an issue)
I have tried using samsung kies and smart switch with drivers and it does not recognise it either
I dont know what else to do can someone help me figure it out whats wrong.
Thanks
I have the same problem.
Is there any way to root note 5 n920v without pc?
My phone have a problem that does not connect to pc with usb cable, my last hope is to try to install a new firmware.
By research, i think its a software problem.
