If I try to use my HTC Desire to test Apps I’m developing with Eclipse, then in the screen where I can choose the emulators and connected devices, it is only listed as unknown and a few question marks.
I read that on Windows you need HTC Sync respectively the drivers in this program, but how can I solve this problem on Ubuntu?
If you never set up the udev rule in linux, the usb connection will not work correctly. There is a tutorial in the official document:
