I have the same problem, DDMS detects the phone correctly, but ADB won't. LanceH, tried your version too, that won't work either. My version was the latest official one from Google!
All of this happened after their platform-tools update...
In Linux, now the 3 adb files have been "moved" to /platform-tools in lieu of /platform, I haven't got it to work either. I need to spend some time finding out why, of course, but why should I have to do that blx?
lance@lance-P67A-UD3-B3:~/android-sdk-linux_x86/platform-tools$ chmod +x adb
lance@lance-P67A-UD3-B3:~/android-sdk-linux_x86/platform-tools$ adb devices
No command 'adb' found, did you mean:
adb: command not found
So, WIn 7 it is for now... was going to Gen 2 the FLB r11 ROM for a laugh, but not in Win VM thanks...!
