Copying Files from PC to Kaiser SLOW

Hello,
whencopying files - let's say some MP3 albums from PC to Kaiser via USB-Sync connection, it takes ages to complete. I guess it's about ~ 300KByte per Second.
I have a 6GB MicroSD Card Class 3 put in the Kaiser and expected a far better speed.
What is your performance?

If you're that concerned about speed, use the 6 GB card to transfer the files. Copy them from the PC onto the card using the USB reader you should have gotten with the card, then stick the card into your Kaiser.

I'm also wondering why the speed is so slow. The manual indicates that the Kaiser has "USB 2.0 Full-Speed". So why is it so slow? Doesn't support ActiveSync/WMDC USB 2?

Coping large files via Activestink has historically been slow. And on older HTC phones would cause disconnects. Two options is to use a card reader to transfer large files, the other is to use Softick Card Export to convert your phone into a card reader.

I already use Softik Card Export and I really love it. Maybe it is a little bit faster, but it doesn't exceed the USB 1 speed...

I just did a test with my TyTN II and Softik Card Export - not more than 1Mb/s. closer to .7Mb/s actually. I tested the USB cable with my portable USB2 drive and it was 25Mb/s - so the cable is fine.
I've emailed Softick to find out if USB2 is supported, or ever will be.
Will post here when I get a reply.

However, Softick Card Export is MUCH better than ActiveSync.
I'll buy it right now...
Thanks !

How to get USB 480Mbit (USB 2.0) Speed ???

Hi,
the Kaiser has USB-speed specified with 480 Mbit, but the speed to put onto it some MP3s via ActiveSync is not much faster than with my Magician (USB1.1) before. If I put in my computer directly the MicroSD card (max 5MB/sec) it is much faster although 5MB/sec << 480 Mbit. So the weak point is not the card. Is there any idea to increase the speed filling my card via direct USB connection ?
Thanks in advance !
Best,
Hugo

Your usb data speed depends on what your com port is set to. if you have alot of usb ports then they share the bandwidth between them. so you may only get 20% of your actuall bandwidth if you have a few other usb devices sharing the bandwidth. you can go to your device manager on your pc and increase the percentage your com port uses of the bandwidth

Thanks for your answer,
and you may be right, if I had a lot of devices conncted to my PC. But I have not. The point is: If I put the microsd into an USB adaptor and connected to the PC, it is quite fast, if I took the Kaiser connecting it ti the same USB, it is slow.
Any other thoughts?
Best,
Hugo

This holds true for all PDA devices connected via USB...not just the Kaiser...activesync may be the bottleneck.

Ok,
if ActiveSync may be the bottleneck, how do you work around this slow copy-process? With CardExpord it is quite faster than with ActiveSync (thanks for the hint), but still far away from the limit :
To copy 58 MB from PC to Magician via CardExport - it needed 94 sec
58 MB from PC to Kaiser via CardExport - 69 sec
58 MB from PC to Kaiser via ActiveSync - 235 sec
58 MB from PC to Card via USB Adaptor - 12 sec = 39 MB/ sec
Anybody any idea to increase the speed of CardExport, there is still much room left ?
Thanks for that discussion!
Best,
Hugo

Most SW connecting to your PDA for file transfer do it through Activesync which as stated before is a bad bottleneck (its sloooow).
You are also using the file handling system of the PDA via this method and any number of background tasks will slow this down.
WM5torage (there is a thread running on here) gets around using Activesync so it may be worthwhile contacting the author to see if this will work for you or wether it could be modified for your purposes.
Hope this helps.

Read the specs carefully. It says "USB 2.0 Full Speed". Don't confuse Full Speed (12 Mbps) with High Speed (480 Mbps). What HTC is doing when they say this is commonly called "deception"!
Has anyone tried ActiveSync over Bluetooth to test whether the Kaiser supports EDR?

Ahhh, abu, you seem to be following me to flame!!
Let's just help people please???
EDR (Enhanced data rate) is fully implemented on this device as was not the case with the TyTn (Hermes) and you will find some of my old threads in there about this very subject that you have placed within this thread ( not whatsoever to do with the first post I may add!!)
OH flippin eck! the wine is taking over.

even usb harddisks max out at about 30MB/sec
and as pda's cant keep up with fast flash cards
it's silly to believe that pda's could keep up with
usb2 speeds

I love your sig file lol...

Hey good discussion,
I am a bit disappointed of the advertised 480 Mbit (ok in manual there is mentioned USB 2.0 full speed) but I can only see an advatage of 25% against my old Magician with USB 1.1. and even 12 Mbps (USB 2.0 full speed) should result in douple speed as the measured. I did not expect 480 Mbit, but a bit more speed, than currently offered.
Best,
Hugo

well chicks dig it
well some would be bound to somewhere somehow

Sorry Farsquidge, that my comment about video driver issues was spiced with a pinch of sarcasm. But here I am trying to be purely factual.
EDR is clearly mentioned as supported. I haven't tried this myself yet. But this will probably be slower than ActiveSync over USB as Bluetooth 2.0+EDR is 3 Mbps compared to Full Speed USB at 12 Mbps.

Note that they never advertised "480 Mbit". When they say Full Speed then that means 12 Mbps. That they throw in "USB 2.0" in front of this is IMO not entirely honest.

Yep, it could be taken as misleading.
I have never actually synced with BT as I only have my usb cable at work but I have just tried it and it seems much faster than cable connect. May just bring my charger from now on!

USB speeds are the maximum theoretical badwidth of the hardware, and are much highe than what can actually be achieved... Throw in ActiveSync, and USB speed is virtually meaningless...

Understood,
USB 2.0 was missunderstood as 480 Mbit by several (!) professional journals and websites testing mobiles and PDAs and -reading that- by me. Ok my mistake - next time I will directly come here and look for spec...
What I read in the threads above is:
"Mobile has USB 2.0, but do not expect 480 Mbit as it's only full speed, but don't be silly to believe to get real 12 Mbit as there is a big difference between hardware and spec. You really have to be satisfied, if you get real 6.5 Mbit, which is 25% faster than the USB 1.1 Magician."
In the end I am happy, not to get slower...
Thanks for discussion,

Insanely Slow Data Transfer over USB

hey guys,
ever since i got my tilt, data transfer over USB has been painfully slow. for example, a 900 mb tomtom map took over 2 hours to transfer. I tried taking the SD card out and putting it into my laptop. everything transferred in less than a minute, but as soon as i put the SD card back into my tilt, it turned out it was corrupted. i tried searching for a solution to this issue, but couldn't find anything.
halp

you say ever since you got your tilt does that mean that you had other and faster transfers on other pda's because in my exp thats the case with all wm devices

no, this is my first WM phone, and first PDA ever (i had an i870 before)

activesync is slow period, i use a mediacard reader,i highly recommend a storage card and is SDHC and a compatible card reader for your laptop/desktop,can also find cards on ebay with usb readers instead of card readers so you can just plug the card into the usb stick and away you go

unfortunately that's how the USB plug works on these phones. It's USB 1.1 only.

it's not just a usb1.1 issue as usb1.1 should be able to do 12MB/sec which is far from what happens in reallife

To give you an idea, I just did a quick and dirty test of the different transfer times.
RAR: 41.7 MB
Using Activesync:
- Copy to internal memory => 01:05
- Copy to SD Card => 01:20
Using Card Export:
- Copy to SD Card => 00:51 (mean transfer rate: 850 KB/sec)
Using USB Card Reader =>
- Copy to SD Card => 00:04 (mean transfer rate: 12500 KB/sec)
Conclusion: Always use an external card reader for transfering (large) files.

Tytn II has usb 2. Why the speed is so lame then?

The Kaiser is my first device, so I don't have any other devices to compare to. But in a large degree I have noticed the same for other mobile devices (like cameras, mp3-players,...)
It has to do with some factors:
- What app is used to transfer the data?
Working through Activesync to transfer data clearly works slower. That's because AS works as just another layer controlling the data transfer, thereby slowing the process. When you use Card Export, only the regular explorer.exe process is used for tranferring the data.
- Chipset limitations:
It might be that the Qualcomm chipset has a slow MicroSD and USB controller. Manufacturers also have to choose between better battery life or more speed. Mostly better battery life is chose, thereby bringing down the speed.

My old Dell Axim x50v used to sync calendar/appt within 5 secs. But my tilt takes atleast 1 min everytime to sync calender/appt. It takes that long before the sync icon stops spinning and states connected. Do you guys have the same problem?
btw, transfer speeds for data are the same between the two pdas. its just the sync time.

It is always painfully slow to transfer files with activesync, not just the Kaiser but with all PPCs. As far as sync with outlook that is really poor with WM6 and Activesync 4.5. I think I read somewhere the reason is that activesync runs very in depth checks on changes and date comparisons resultuing in long sync times.

my main problem is not that the tilt is soo slow, but why is my sd card getting corrupted EVERY time i put it in my computer? when i copy a decent size file, all the other files are fine, but that one explodes its size like 10x and takes up 90% of the card. my only option is to format every time

weakest link set the pace
if usb2 is supported then there most be a bottleneck
elsewhere
it imho seem to have been an issue with every pda ever

[Q] (Very) Slow File Transfer Over USB Cable

I'm using Total Commander 8.01 with ADB v6.9 plugin (latest as of now) and file transfers over the USB cable peaks at 1-1.5 MB/s. MTP mode over WinExplorer doesn't have transfer speeds displayed, but I'm perceiving them as about the same.
It's the same whether to/from phone or internal/external SD. Had both storages benchmarked within the phone (SD Tools on Market) and they averaged far above said speed, especially external SD which is UHS1. The USB ports on my computer are good and proper, besides the phone does the same on other machines.
Before someone asks, I have no convenience of wifi signal everywhere. Secondly, the phone is often charged over USB and I want to use the already present connection to transfer files.
Running Stock V20B.

Am I really the only one with this problem?

Starting the same 10 battery & boot probs threads a day is fine, but posting one reply here isn't. Come on, someone!

Maybe using another cable would solve this...?

I only copied files over USB once but it was indeed terribly slow. I don't recall exactly, but I think it was about 600kb/s.
I am not on stock and using Ubuntu. So the problem is not just your setup...
Edit: Ok, so I copied a rom to my device today, it went fast. 100mb in a few seconds...

Thank you for replying.
I tried another 10cm cable (minimal loss of signal), another computer, USB ports directly on motherboard (got to 2.5 MB/s on either storage) and no changes.
Maybe there is some setting in the phone I should turn on or off that I don't know about? I don't know what else to try, short of flashing a custom rom (no guarranties that would work at all).

I have USB debugging enabled today, don't know if i had this enabled before. You could try if this makes a difference?

Unfortunately, ADB plugin for TC requires debbuging enabled to function. I doubt it'll make a difference, but I'll try it with WExplorer in MTP mode.
Well, USB debbuging made no difference, but MTP mode reached 8-9 MB (better, but still way below what it should be), while ADB+TC says it creeps at ~3 MB.
Same file copied via MTP needs 3.5 mins and ADB plugin requires for stumping 16 minutes! And that's on extSD, not internal. So, ok, the TC plugin is a decomposing cadaver, fine, but that doesn't account for MTP's speed.

Question Is there a faster way of communication between oneplus and desktop.

Trying to look at pictures on computer (been taking lots of them with this camera)
accessing data is stupid slow and it doesn't make sense
phone unlocked with allow data transfer selected
oneplus charger to usb b port at front of case "equally as slow with usb c at back of motherboard" so I dont think the cable is the bottleneck
I feel like ive tried everything including enabling usb debugging (dont know why but I havent been into tech to the level of this amazing forum since I was young so forgive me if answer is obvious google was useless)
Thanks, D

to clarify transfer is what to be expected but the loading of thumbnails and data amount or size. once youve loaded all of them its fast.
but it takes a few minutes sometimes.
phones generally have good SSDS so does my computer processors on the phone is good, I cant find the bottleneck, does every device do this???

Windows need to read all your photo, every time you connect the phone. And if you have many photos... it could take some minutes ...
For example my Lenovo Legion y540 with i7 gen9 12mb cache, 16gb ram dual chanel, SSD Samsung 980 Pro 256gb for Windows & Samsung 870 Evo 2 Tb for storage. In my case it takes a few minutes. 2, 3 -5 minuntes. Yes is annoying !

If you use the stock Oneplus red cable between the phone and the desktop, it most likely is a 2.0 spec C-type cable (most likely, at least the one that came with my 9 Pro is). Go buy a 3.1 C-type cable (nowadays USB 3.2 Gen 2) or 3.2 C-type cable (nowadays USB 3.2 Gen 2x2)

That's annoying, I thought the point of a thumbnail was a low res picture for quick access. You'd think in 2022 we'd have a better way.

Ok so at 2.0 speeds 480 Mbps, suppose all pictures are 15 mb big and they're 1500 of them I'd take 48 seconds to see them all (high res no less)
(But they're not because you click on them and it takes an additional 7 ish seconds to load the image when opened. )
By this logic using a 3.0 cable (4800mbps) ( if ssd supports the speed) should only take about 5 seconds for all images
And it does not because I've used a c to c pixel cable to connect.
So they're must be a software bottleneck preventing a few things
The thumbnail should be small and in turn it should really take no longer than a couple seconds to load low res images ( unless these thumbnails don't exist on the phone and they have to be generated once the phone is plugged in)
It could also be a Windows issue (anyone have a mac that could try accessing their data through the file browser) just like the search feature in Windows takes ages and it's often so bad it can usually be faster finding the file manually it could be a matter of a broken or outdated protocol to read files off a device.
All I'm saying with all of these advertised speeds 5 minutes for 1000 5mb (yes not 15) and a couple big videos is too damn long. I'll be trying to see if there are any softwares out there that let you read of your device in a similar way itunes ( does itunes still exist??) does with apple devices

I have a usb3 10gbps cable and it still runs at slow speeds. I think that it's only USB 2.0 over type C

Maybe the 10 Pro has slower USB type C then, my 9 Pro is way faster with a 3.1 cable.

are using a usb 3 port on your computer?
i don't have any issues with transfer speeds.

I forgot to mention, my laptop have only usb 3.1 ports & 1 type C for charging.. & Windows 11 Pro x64.
Type C ports are produced in different versions, from 2.0 from 3.2.
Thumbnail are not the problem. I set my View with Details & select the newer first. Same amount of time. Still the green bar charge all hundreds of photos. Like i have a hdd from 20 years...
