Take the 2-minute tour ×  I recently installed CyanogenMod on my
Galaxy Ace and now its USB tether option is not working. The
phone is detected by my PC only when I check the USB debugging
mode. I can tether with external applications like Easy Tether
but earlier USB tethering was built in for my phone when I had
the Samsung stock firmware. What could be the possible problem?
share|improve this question It could be that CM's USB tethering
feature is unsupported on your device (discussed a bit here: USB
tethering with Cyanogenmod 7.0.3) –  eldarerathis May 18 '12 at

are complete. They are always under major refactoring and
between minor revisions major functionality may be broken. For a
long time I have been using custom roms, and if some
functionality is broken I would advise you to return to a
previous version of the ROM, or switch to another ROM.  The
problem can also be related to the kernel you are using. Kernel
is different than the ROM. RO
