Any details on the power supply driving the hub? My recollection is that you should
plan on a minimum of 1A @5V for each BiFury when running at it's normal low clock
speed. I think it can go as high as 1.8A.
A few other debugging thoughts:
- How long will it run with just 1 BiFury plugged in?
- How long with two?
- How long with three?
If shrinking the number of BiFurie's makes things better, think power for the hub.
It seems that i will run for much longer with less number of devices.
I think this hub it is defective by design and cannot provide more power to each of the usb than
0.5Amp.
The power supply which is used is 12V DC, 5A. Shall i try it with a stronger power supply?
I may give it a try with dwc_otg.speed=1.
