-Q: On linux I can see the /dev/ttyUSB* devices for my Icarus FPGAs, but
-cgminer can't mine on them
-A: Make sure you have the required priviledges to access the /dev/ttyUSB* devices:
- sudo ls -las /dev/ttyUSB*
-will give output like:
- 0 crw-rw---- 1 root dialout 188, 0 2012-09-11 13:49 /dev/ttyUSB0
-This means your account must have the group 'dialout' or root priviledges
-To permanently give your account the 'dialout' group:
- sudo usermod -G dialout -a `whoami`
-Then logout and back in again

 Q: Can I mine scrypt with FPGAs or ASICs?
 A: No.
