+# Unstable connection
+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.
+* is it working with LED disabled? LEDs are triggered from host over USB. Looks like some host controllers don't like it. Use this command "sudo bash -c "echo none > /sys/class/leds/ath9k_htc-phy*/trigger""

# 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.
