+# Unstable USB connection (ath9k_htc: USB layer deinitialized)
We get some bug report about unstable connections and different weird issues. Before reporting a bug, please check:
* is it working with other (shorter?) cable? This HW seems to be picky about cable quality, so check it.
* is it working with powered USB hub? People had issues with some specific usb controllers. Test on other HW if possible, or at least find some cheap powered usb hub.
`sudo bash -c "echo none > /sys/class/leds/ath9k_htc-phy*/trigger"`
+# BOGUS urb xfer, pipe 1 != type 3
+If you get this error, then you need to update firmware (at least version 1.4) and kernel (at least v3.18). If you still get this issue, ask or check if your kernel really has this patch "ath9k_htc: do not use bulk on EP3 and EP4".

# USB Suspend (Firmware issue)
Currently usb suspend is not working, instead of suspend firmware will reboot. If we are lucky,
firmware will set device to lo power mode and reboot on resume.
