My USB Endoscope works flawlessly on my old Note2 plugged into its USB connection, however when plugged into the USB connection on my Ele’ 9000 all I can get is the message ‘No USB camera found’ anyone have any ideas I could try?

when I connect the USB cable onto the computer the USB notification fails to appear and the charge indicator doesnt work. The USB cable works as I had just unlocked the bootloader but now the USB does not work and I cannot charge!
Anyone ever come across this problem? RSD still detects though so I guess there may be hope
hi XDA
I am having some strange behaviour with my USB OTG...
- charges OK
- connect USB OTG cable: phone says "USB host cable connected"
- connect a memory card reader: nothing (used to work previously though)
- connect a mouse: nothing (used to work previously though)
- plug into official Samsung car dock: car dock enabled, but only one stereo channel working (right channel)
- plug into PC: Windows says "unrecognized device"
..... SO
I was thinking: something wrong with my hardware
so I ordered a new USB hardware module on ebay
and I successfully fitted it
...however
...still no change ???
looks like it wasnt a hardware problem after all
USB debugging on or off: no difference
Anyone got the same or similar issues? OTG is a really useful feature for me so I hope I can fix this
Try plugging the card reader or whatever into the OTG cable, then plugging the other end of the OTG cable into the SGS2. That seems to give a much more reliable connection in my experience.

It is not the first time I am trying OTG. This summer I was travelling and posted >100 pictures to my blog. The correct order was: cable first, then memory card reader WITH memory card already inserted... in desperate attempts I tried several other combinations but without luck.
I have a P769 Tmobile running V20H
When I plug into a USB 2.0 port, the phone trickle charges, usb connects, etc, everything is fine. When I plug into one of my USB 3.0 ports however the phone just charges and doesn't connect. I want to be able to connect to a USB 3.0 port. I remember it did once, but I believe that was on an older ROM. Other phones connect to the USB 3.0 perfectly fine, so I don't think it's the PC's problem.
Does anyone know the solution to this?
Today, after really much try and error, I experienced that mtp mode does NOT WORK with my Anker USB cable. The other USB modes work but device manager will show code 10, cannot start device or something, when using the Anker cable.
Did anyone experience something similar and more important, can anyone recommend an USB cable that duly works?
Yesterday I had my Mi 11 Lite delivered. After setting up the SIM card and so on, I tried to connect it to my Windows PC to copy the photographs that didn't migrate during the device transfer procedure.
Plugged it into the PC, it failed to appear in file manager. It started to charge, but wouldn't connect otherwise. Tried all the usual of setting the default USB, turning on USB debugging, nothing. Tried various different USB sockets, USB hub, nothing. Getting very frustrated, I was thinking I would return it for a refund. By this time it had downloaded an update and requested a restart. As it restarted, it was plugged into a USB port and once I unlocked it, hurrah! It connected. I then copied over the pictures. Happy days.
A little later I re-connected it to the PC and again, nothing. I installed the Xiaomi connection suite and it complained that there was no device connected. Eventually I installed Smartisan's wonderful Handshaker which creates a WiFi connection and copied over some files using it. I was still annoyed though. This morning I thought I would try connecting using my Laptop. No connection there either. I tried a USB OTG flash drive, it wouldn't work. Thinking I really would have to return the 'phone, I rebooted it. When it restarted, I plugged the USB OTG drive in and this time it appeared. Plugged the 'phone into the PC, nothing. Plugged the OTG drive back in, nothing again. Rebooted it once more, USB OTG worked. Thinking I was starting to go crazy, a thought suddenly struck me.
When I had plugged it into the PC the very first time, I had plugged it into a USB-C port on the PC. When it restarted, it was plugged into a USB-A socket as that was the last port I had tried. As the USB-A port had worked, I had then tried the USB-C port, which didn't work and after that nothing connected to the 'phone worked.
My PC is a Lenovo all in one which should allow use of the screen and keyboard to be shared with a mobile device when plugged into the PC's USB-C port. My guess is that the PC is trying to connect to the Mi 11 Lite, offering to share the screen and keyboard which then confuses the 'phone and blocks all access to the USB on the 'phone until it is rebooted. Since I have avoided using the USB-C port on the Lenovo PC to connect to the 'phone, it has worked perfectly well.
Steps to try if your 'phone won't connect to the PC:
Unplug all cables from the 'phone and reboot it.
Make sure that the USB-C cable is removed from the PC.
Plug a USB-A to USB-C cable into a USB-A port on the PC.
When the 'phone has restarted, unlock it.
Plug the USB-C end of the cable into the 'phone.
I should add that I have been using the USB-C port on the Lenovo for all my other 'phones, including a Mi Mix 2S, TCL 10, Carbon Mobile and a Teclast Tablet and all have been fine. Only the Mi 11 Lite has not worked as expected.
I hope this helps someone. It may just be something that is specific only to the Lenovo PC and the Mi 11 Lite 5G combination, but it has had me baffled for hours!
I have the same problem, I would try your solution but my Asus laptop doesn't have a USB-A but only 2 USB-C ports and no way it connects. It works ok with my pc which has an USB-A port.
So I think there's no solution for me?
Also I have another
I have an issue with Bluetooth, it doesn't automatically connect to paired devices like my car (most importantly), speaker or laptop. First I thought it was the car but since it doesn't auto connect to other devices it must be the phone(s)
I have searched for a solution on Internet but couldn't find a fix. BTW same problem on my Poco F2 pro and Oppo X2pro. All are global rom.
Has anyone a solution for this problem?
