Background:

Phone OS:
Evo 4G, unrooted, latest OTA update.

Computer OS:
Fedora 13

Just noticed that issuing an 'adb reboot recovery' seems to load the correct screen on the phone - the red triangle/exclamation point.

'adb devices' shows the HTC* offline.

adb kill-server / adb start-server shows the same thing.

Going into recovery mode 'manually' (aka Vol Up / Power at boot, then loading to recovery) adb devices still shows nothing.

Will try from a Windows PC on Monday just to verify it's not a Linux issue, but curious if anyone else has run into this? Hoping this isn't something else the OTA screwed - already pissed that my stock Android Launcher was removed (running LauncherPro now, so eh - thanks HTC?)

Sorry for that. So the update 'fixed' this? No way around it, I suppose?

That happens to me occasionally. Usually I remedy it by some combination of switching between disk drive mode and back to charge only, or rebooting the phone, and sometimes switching usb ports.

sorry thats all I can offer

It seems many of us are affected by this "adb devices offline" trouble :

I had to plug the usb cable again to put the device online,
but do you know a way to reset the usb bus of a linux box ?
