#19195: Can not turn off USB power by hand on TP-Link TL-MR3420 v2.3
---------------------+--------------------------------------
Reporter: tischd | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: kernel | Version: Barrier Breaker 14.07
Resolution: | Keywords: mr3420, gpio, usb, power
---------------------+--------------------------------------
Comment (by tischd):
2 extra info:
* all the same with CHAOS CALMER (Bleeding Edge, r44797)
* interestingly enough after I issue "echo 0 >
/sys/class/gpio/gpio4/value", the USB LED fades a bit, and if I enter
"echo 1 > /sys/class/gpio/gpio4/value" it comes back to its full
brillance. But "cat /sys/class/gpio/gpio4/value" always gives 1, and USB
port is powered constantly.
