The patch above is bad; the correct product ID for BLUE bean is 0x9378. 
QCA9377_1_0_DEVICE_ID in hw.h also needs update. (Or perhaps add a 
QCA9377_1_1_DEVICE_ID)

I have now done many tests using both BLUE bean as well as the Linksys 
WUSB6100M, without success. I've created custom firmware and board files 
based on the instructions on 
https://github.com/erstrom/linux-ath/wiki/Firmware, so that shouldn't be 
the problem. Tested both the https://github.com/erstrom/linux-ath.git and 
https://github.com/kvalo/ath10k.git master branches. Regardless, I get the 
same kind of error:

[   35.350683] usb 1-1.2.1: Failed to submit usb control message: -110
[   35.350686] usb 1-1.2.1: unable to send the bmi data to the device: -110
[   35.350687] usb 1-1.2.1: unable to write to the device (-110)
[   35.350688] usb 1-1.2.1: settings HTC version failed
[   35.350691] usb 1-1.2.1: Could not init core: -22

I have seen https://github.com/erstrom/linux-ath/issues/6. This is the 
same type of problem I believe, except that I'm not trying AP mode.

My conclusion is that ath10k with QCA9377-7 (USB) devices are not working 
a this point. Just as 
https://wireless.wiki.kernel.org/en/users/drivers/ath10k says :-)


Will try SDIO based RED bean as soon as it arrives.
