When I'm trying to connect a USB device like a USB WiFi dongle or Pendrive with a homegrown USB breakout by soldering 4 wires to them, it's just not working.
I'm running Ubuntu and getting errors like this,
hub 1-1:1.0: unable to enumerate USB device on port 3
Above line is not the exact same error message, I can post them if needed.
But low speed USB devices like a USB AVR programmer is working fine.
ehci-pci kernel driver is being used for both high-speed and low-speed USB devices.
So what's the problem with high-speed devices ? Is there any way to fix this problem ? Probably extra capacitance and inductance from the DIY breakout is violating high-speed USB specification, am I right ?
