Hi,
I just find a quick and dirty patch to workaround this issue.
I just reset the device on initialization failure.
I hope this helps to understand the real issue.
[ 7.012514] usb 1-7: firmware: requesting ath6k/AR6004/hw1.3/bdata.bin
[ 7.035276] cfg80211: World regulatory domain updated:
[ 7.035287] cfg80211: (start_freq - end_freq @ bandwidth),
(max_antenna_gain, max_eirp)
[ 7.035299] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz),
(300 mBi, 2000 mBm)
[ 7.037916] usb 1-7: firmware: requesting ath6k/AR6004/hw1.3/fw-3.bin

[ 9.379054] ath6kl: f59afe6c
[ 9.379391] ath6kl_usb: probe of 1-7:1.0 failed with error -5
Here I reset the device.
