Eclipse not detecting HTC desire as device

I've been developing an Android app on Ubuntu 10.10 with Eclipse (using HTC Desire) for the past few months without any major problems. Today however, I was testing some stuff and for some reason Logcat wasn't outputting certain messages (timing logs to measure performance). So I foolishly thought there might be something wrong with the adb connection. I went into the phone settings and unticked USB debugging and then re-ticked it. Now Eclipse will refuse to detect the device.

I have the proper udev rules set up, and I've tried restarting both the phone and computer to no avail. Changing USB ports doesn't help. Like I said, this was working fine for the last few months 开发者_如何学Cand now all of a sudden because I reapplied a setting, it went kaput.

Fixed it. Had to do a factory reset on the phone. No biggie but annoying nonetheless.
