Hi Oleksij,

I put 4 ar9271's on a 4 port hub into monitor mode for you and all
interfaces are simultaneously collecting packets. My cheap USB power
meter reads 4.37v@650mA between the hub and the host, so it's pushing
the limit but appears stable.
Great work, thank you!

The usb_*_msg() functions expect a timeout in msecs but are given HZ,
which is ticks per second. If HZ=100, firmware download often times out
when there is modest USB utilization and the device fails to initialize.

Replaces HZ in usb_*_msg timeouts with 1000 msec since HZ is one second
for timeouts in jiffies.
wow..
This fix allow you use 4 adapter at same time?
