hello guys!i have question,what is this 'USB host mode'??i see this on my hd7where hold button power+vol.down+camera.Please reply...sorry my English
When you have a USB connection, one end acts as the "host" and the other acts as the "device." Typically standard "computers" (desktops, laptops, etc) act as hosts and what you plug in acts as a device. However, some devices that support USB On The Go (OTG) can switch between host mode and device mode.
When a device is in host mode, if it has the appropriate drivers, you can do things like plug in keyboards, mice, thumb drives, cameras, etc and control them from the host mode device.

hi i was wondering if anyone out there new if there was an SDIO USB HOST card, similar to the shown on the link below (but obviously SD not CF)
http://www.ratocsystems.com/english/products/subpages/cfu1u.html
if not, does anyone know/have tried the above CF to USB Host with a standard usb webcam and got it to work? if so can you explain how i go about setting it up.
thanks

i'd suspect that the fact that usb to host have to supply 5volt with 0.5mA
it could be an issue for something as thin as an sdcard
also not sure if the sdio interface even operate at 5v
usb host
I haven't seen an sdio to usb card, but I use my "htc universal" with it's mini usb as a usb 1.1 host. It works ok but you have to supply external power.
if you have that working you are the first and only person i know of who gotten any htc device act as usb host
sure there were rumors that it would do host
but later on ppl retracted those claims
After wiring up a cable for that, how do you set the phone to 'host mode'?
Thanks
usb host is not a mode
your pc is in host mode always
as are the 2 htc devices which do support
usb host out of the box
is a device is connected and the driver
is present the device works
Nope, USB host is a mode. It's the whole Master / Slave affair. Granted, it's automatic for most devices when another is connected... ah... that ought to answer my question I guess.
Hello, now making my USB OTG cable from nothing. Saw in the "USB Host Controller" 's settings that I can change "Operation mode" to either "Host" or "Client", not only "OTG". Does this mean that my device can enable its host capabilities without connecting the "right" OTG cable with 4&5 pins connected?
Yes. OTG mode only means it will detect the operation mode automatically.

Click to expand...
Click to collapse
I made a few of these cables, OTG and audio line outs (fun with resistors had me soldering and making cables for a week lol)
USB Host Controller is just a helper app, You still need to short the pins for the cable to work, as well as making it a "powered" cable since the cappy wont power OTG compatible devices that need it.
Sony advertises the c6602 as being able to do USB Host Mode. I ran USB Host Check, and Android.hardware.USB.host.xml was found, but, handheld_core_hardware.xml was not. I'm assuming this is why when I attempt to connect a USB device (nooelec USB sdr) i'm having issues working with the device even though I have the RTL2832U driver installed/configured.
I have not rooted. I'm assuming that the other xml/any other needed libraries needed to be able to power the device have to be installed in order to run this device without connecting it to a USB hub that is already powered, or? I tried to take a USB hub, plug the cable into an IPhone wall adapter so it'd have power, but, I had the same results.
Thoughts? I should still be able to use the device if I have an external power source, no?
I'm considering to add a powered hub to my Hui because i want to connect a usb flash drive, a dab dongle, a hard disk and maybe a wifi dongle and i want to charge my cellphone.
Right now i have an unpowered USB hub connected to my usb storage port 1. When i connect 2 usb sticks to the hub only one is detected in android, when i also connect my dab dongle, my dongle works. When i remove the USB sitck which is not working and i plug it in my USB 2 storage its also not found ( in root explorer a white icon appears before the name "usb_storage2").
Can some one explain me why the USB storage devices are not mounted / found in android? Is it even possible to add more than 2 storage devices or USB devices to our Hui? Or do i have to mount a third USB storage device manually?? Or is it because o the less of power??
I don't think android currently supports more then one USB data device. I know there are workarounds but I have not tried any. Most of these devices come with at least one sd slot so I think most (myself included) just live with the one usb limit.
Hi,

It sounds like the USB port may actually be bad. Is this tablet stock? If you have TWRP installed you may try connecting it from recovery. You might also try from Linux booted from a flash drive to take Windows out of the equation. The data pins and the power pins or separate, so it may just be that the data pins have been damaged.
Does the cable feel loose in the tablet?
