host mode and power Supply - help! - Desire Q&A, Help & Troubleshooting

I Have:
Cyanogenmod 7.1 rom
Kernel: 2.6.37 cyanogen 7.x Kernel Patched with USB Host (from here)
Desire GSM phone
OTG cable
USB Y cable (to male and one female) - picture in attachment
And two problems!
The FIRST problem
This kernel enable host mode, when load command in terminal.
I typed command but, I have error:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I searching dev/bock but there is no sda1 or sdxx..
The SECOND problem
Maybe I have problem with power supply?
I tried to attach in computer port, usb flash drive lighting and copmuter recognize and open..
And I tried to attach to usb charger and nothing happen. Flash doesn't light...
Any help please!

This looks to me as if you connected the cable wrong... usually the male connector with the two cables coming out is the one for data and the other one is the one for the power.
Try connecting your USB to Micro USB cable to the other male connector...
To be sure the cable is working correctly, try connecting the drive via your y-cable to a computer. That way it's easier to find out wether you are using the correct plugs. Also in this case, don't plug in the second male cable, b/c the computer USB port should already give you enough power.

Finaly works!
Yes, you were right. I reverse usb male connection devices.
I loaded kernels again, but there is no sda in block folder.
So I used USB host controller app, and mount usb from here and works.
Picture in attachment.
But I don't know where is the path to my sda?
On this picture says sda4?
I tried this
HTML:
mount -t vfat /dev/block/sda4 /mnt/sdcard/mnt/
but have same error - no such file or directory

Ok, the first question sloved (almost)
Another question:
Where I can get power supply, maybe usb battery to give a power to flash drive?
I don't want a adapter or charger, I need portable usb power battery for traveling.
Anybody have idea where I get this?

USB OTG will be enabled with an update, this has been confirmed on g+ by a googler. In the meantime I use the latest MCR rom from modaco.com and USB OTG works fine

This is probably less about USB OTG host mode as a feature and more about how ICS handles auto-mounting storage attached to it hence the "host mode experience" isn't 100% yet, even though host mode and HID work fine with the right kernel.

[Q] OTG not working - Cable or Software Issue??

I'm very new to all of this and am not sure what I am doing wrong. I can't get my USB hosting to work. I have run USB Hosting Diagnostics and have included screen shots of what it says. If I'm reading it right, it is supported, but the Android API (Cyanogenmod 10.0?) isn't recognizing it. How do I fix this, is it a faulty cable or a software issue?

as you are using cyanogen mod, it does not include any app to automatically mount the usb otg device. So the best way to overcome this is to install an app like stick mount from the play store, which can automatically mount your usb device,. Also note that NTFS file system is not fully supported, so make sure that the device you are trying to connect has a fat32 file system...

I tried stick mount and it also didn't work. I would like to be able to use a thumb drive, but the main purpose is to connect my OBD 2 USB to the Torque Pro app. I've tried to connect a mouse, a thumb drive, and the OBD 2 adapter. I've tried using StickMount and USB OTG Helper. Nothing has worked. Any thoughts?

Hey there, sorry for the late reply,, I have installed AOKP JB MR3 on my device and all works well. I tried using mouse and a USB stick today, and it works well.
So first make sure that the OTG adapter is not faulty (try using it on some other device).
If the OTG adapter is okay, try changing your ROM. Some builds of CM ROM have bugs some time, especially if you are using a nightly release (Just backup everything and flash the latest official AOKP ROM. See if it works there).
Try changing the kernel if you are not in the mood (read feeling too lazy) to change ROMs. Your current kernel dev might not have implemented the USB Host module properly and this can also result in a non-functional OTG device.

[Q] How to mount WD Elements?

Are you using a powered USB hub? The Nexus probably doesn't put out enough juice to power a hard drive.

It is possible...
I use only ordinary OTG cable...
So I will try to search some powered OTG cable...
Thank you again @meekrawb
I bought this:

And now is working, but it would be better if it will work without power.

poor nexus 7 cannot provide that amount of juice for ext HDs
I have the same HDD and it works fine. I installed the ElementalX kernel, which provides NTFS support, and used Paragon NTFS to mount the HDD (available on the play store). I have a different problem myself: As soon as the device is locked, whatever is being streamed/accessed from the HDD is no longer accessible and the HDD has to be disconnected, reconnected and remounted.

Nexus 5X malfunctioning on PC (USB)

Hi, I have an LG Nexus 5X and a new USB cable. I'm trying to connect it to my PC. Using the new USB. When I plug it in I get an error that "the device malfunctioned and Windows does not recognize it." It doesn't show up under "My PC." I tried "Allow USB Debugging", changing "USB for Charging" (I don't get the option for "File Transfer", just "Media Transfer" "Picture Transfer.") I tried them all. I'm trying to root my phone. So why doesn't my phone show up on my PC? Is it the USB Cable? Why doesn't it show "File Transfer" under "USB for Charging" options? I'm attaching screenshots.

I'm back, I bought a new DataFast-Charge cable. It says I can sync and move files between my phone and PC and vice versa. Any ideas on how to get my phone connected? I have a few days before I get my new cable...
Hi, I'm back. I bought a new USB to USB C Sync/Charging cable. Still saying Windows doesn't recognize it. It doesn't show up under "My PC." Has anyone heard of this problem? No File Transfer USB option. Just Picture, Media, Ethernet RNDIS, Charging, Audio Source, and MIDI. Any ideas? Other settings?
Success! It shows up on my PC after changing USB to MTP. I used a YouTube tutorial and unlocked and rooted my phone. This is solved.

I ruined my phone

It is difficult to explain what happened. It was quite irresponsible of me. I didn’t research it properly before wiping my phone. Now my zuk folders are not showing up on my pc, and I can't format it using TWRP. I was on a Custom Rom with Android 10 and went to another with Android 8.1, just to test it. I didn't like it and was about to install one with Android 9. When the problem happened.
I tried to install the drivers for the zuk z2 plus on the pc. My pc recognizes the phone only as a Media Player and does not even allow to create a folder.
I tried to use adb fastboot with qfill but it is not possible to activate usb debugging, so I cannot install a factory stock rom.
It seems I'm just too late?
First power the phone off by unplugging the battery. You can then short-circuit the test points on the mainboard of Z2 (Plus) before plugging USB cable, to enter Qualcomm EDL mode (9008), then you will be able to export data with QFIL's partition manager, or just flash the stock ROM.

This works for me. It works even if the "deep flash cable" (USB cable with its D+/GND pins short-circuited) can't work (because the detection of such deep flash cable is done by SBL in the PBL->SBL->aboot->Linux kernel boot chain).
However, use it at your own risk.

Ty for helping but i fixed my phone. The problem was the TWRP. My last custom rom downgraded my twrp. I used fastboot and was able to flash the latest twrp and voila. Problem solved. Never gonna try to install android 8 again, just gonna stay with 10 before i got myself in more problems.
