Digged into it more, added few printks, after reboot:
[ 521.710000] ath9k_hif_usb_probe
[ 521.720000] ath9k_hif_usb_dev_init
[ 521.770000] ath9k_hif_usb_download_fw - before firmware download
[ 522.210000] ath9k_hif_usb_download_fw - after firmware download
[ 522.210000] usb 1-3: ath9k_htc: Transferred FW: ar9271.fw, size: 51280
[ 522.220000] ath9k_htc_probe_device
[ 522.230000] ath9k_htc_wait_for_target
[ 522.470000] ath9k_htc_rx_msg - endpoint_id: 0x1 msg_id: 0x18
[ 523.230000] usb 1-3: ath9k_htc: Target is unresponsive
[ 523.230000] Failed to initialize the device
[ 523.250000] ath9k_hif_usb: probe of 1-3:1.0 failed with error -22
[ 523.260000] usbcore: registered new interface driver ath9k_hif_usb
after replug:
[ 624.610000] usb 1-3: USB disconnect, address 2
[ 626.050000] usb 1-3: new full speed USB device using ep93xx-ohci and address 3
[ 626.250000] usb 1-3: New USB device found, idVendor=0cf3, idProduct=1006
[ 626.250000] usb 1-3: New USB device strings: Mfr=16, Product=32, SerialNumber=48
[ 626.270000] usb 1-3: Product: USB2.0 WLAN
[ 626.270000] usb 1-3: Manufacturer: ATHEROS
[ 626.270000] usb 1-3: SerialNumber: 12345
[ 626.290000] ath9k_hif_usb_probe
[ 626.290000] ath9k_hif_usb_dev_init
[ 626.370000] ath9k_hif_usb_download_fw - before firmware download
[ 626.740000] ath9k_hif_usb_download_fw - after firmware download
[ 626.750000] usb 1-3: ath9k_htc: Transferred FW: ar9271.fw, size: 51280
[ 626.760000] ath9k_htc_probe_device
[ 626.760000] ath9k_htc_wait_for_target
[ 627.010000] ath9k_htc_rx_msg - endpoint_id: 0x0 msg_id: 0x1
[ 627.010000] htc_process_target_rdy
[..snip..]
So after the reboot, it seems to me, that the device is left in some wrong state:
[ 522.230000] ath9k_htc_wait_for_target
[ 522.470000] ath9k_htc_rx_msg - endpoint_id: 0x1 msg_id: 0x18
[ 523.230000] usb 1-3: ath9k_htc: Target is unresponsive
versus correct behaviour after replug:
[ 626.760000] ath9k_htc_wait_for_target
[ 627.010000] ath9k_htc_rx_msg - endpoint_id: 0x0 msg_id: 0x1
[ 627.010000] htc_process_target_rdy
Endpoint is 1 vs 0 and msg_id is 0x18 and not as expected 0x1 (HTC_MSG_READY_ID).
I'm quite clueless what's going on there, but I hope it helps at least...
