+Q: On linux I can see the /dev/ttyUSB* devices for my ICA/BFL/MMQ FPGA, 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 `whoami`
|
|
|
+Then logout and back in again
