USB Connecting Problem - Android 2.2.1

I installed xdandroid 2.2.1 and everything works fine (except camera i saw that this is fixed with karnel update but I don't know how to do that) and i can't connect usb to PC.
I try install driver with Android SDK but it can't install CDC Abstract Control Model and CDC ACM Data drivers. On notification bar say that USB is connected and USB debugging is connected .Also I install HTC Sync it install all drivers except CDC Abstract Control Model and CDC ACM Data.
I also done this :
adb and usb debugging
To ensure that you are able to use adb and usb debugging you will need to plug in your usb cable to your computer and in winmo select activesync. Now launch haret and once Android is loaded you'll see a notification that will notify you have usb-debugging control and able to use adb.

[Q] device is not detected when plugged in on linux

Hi i've got CM7 installed and android v 2.3.5
I try to plug it in to USB on ubuntu 10.10
It is not detected so i can't mount it .
Also i don't have the option to change usb settings on my device because this option doesn't exist. Putting on usb debugging mode doesn't help also.
Thanks.

USB device offline

I installed all HTC drivers but adb says device offline. is that because of USB 3.0 I use ? Anything else ?
So long as you're using the latest ADB (1.0.31) the phone will ask permission to connect to the PC. If you don't tick this it won't work

Hi ! I post again because when I connect usb key mtp works and if I connect to my mac and go to settings usb parameters and choose transfert files/Android auto that work but never had notification pop-up for choose it
USB is a master/slave protocol. When you plug in an otg cable, your phone's USB controller switches into host mode. Your computer's USB is always in host mode. So your effectively trying to get two master devices to communicate which USB does not support.
