I use an Iconia Tab from Acer to debug an application. I've already used it a few months ago and it worked very well. But as I try to update the project, Eclipse can't find the device connected.
Yes, the usb debugging is already activated. I updated the specific drivers and the tablet is detected by the computer (as I was asked if I want to open it, like it did before). I try to use the adb commands kill-server and start-server, even reboot with adb usb but the result of "adb devices" still is a blank list.
EDIT: Thanks for the answerer to this post, I checked for the periphericals devices (as I did before), but right-click on the "multimedia player" (it was detected as this) and "solve the problemes" by installing again the android interface. Why had it been uninstalled, I don't have a clue, but now, "adb devices" shows it!
