Topic: bfgminer: Inappropriate ioctl for device (Read 697 times)
if I leave out the timeout parameter (ICA:probe_timeout=100) the error output becomes:

This indicates an error in asynchronous serial communication. i.e. In the usb connection.

tcflush sounds like a connection problem to me.
Is there a difference between the icarus parameters needed for older and newer avalon nano?
I have the Avalon3 Nano, rev. 2.0
Anyone else having this problem?

I have a brand new Avalon Nano 3 usb mining stick.
I've ser up p2pool (I don't think there's a problem with that)
I'm trying to start bfgminer with
bfgminer -S ICA:/dev/bus/usb/005/012 -o stratum+tcp://127.0.0.1:9332 -O userxxx:passxxx --set-device ICA:baud=115200 --set-device ICA:reopen=timeout --set-device ICA:work_division=1 --set-device ICA:fpga_count=1 --set-device ICA:probe_timeout=100 --set-device ICA:timing=0.22 --api-listen
Obviously bfminer finds /dev/bus/usb/005/012 (iv'e set group to lp, same result anyhow if i run bfgminer as root)
bfminer somehow does not connect properly to the miner and reports:
[2015-11-21 15:29:26] /dev/bus/usb/005/012: tcflush failed: Inappropriate ioctl for device
