USB OTG doesn't work on beagle board if HUB is used with two different device classes are attached to it about beagleboard

Hi,

We had the same issue.  Attaching a high speed USB hard drive and a full speed
ethernet adapter (rtl8150) together causes packets to drop, and kernel hangs.

The workaround was to add a full speed hub between the Beagle board and the high
speed hub as follows:

Bus 001 Device 004: ID 0bda:8150 Realtek Semiconductor Corp. RTL8150 Fast 
Ethernet
Adapter
Bus 001 Device 005: ID 152d:2336 JMicron Technology Corp. / JMicron USA 
Technology Corp.
Bus 001 Device 003: ID 050d:0234 Belkin Components F5U234 USB 2.0 4-Port Hub
Bus 001 Device 002: ID 058f:9254 Alcor Micro Corp. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

This slows the high speed device to full speed...

thanks,

Mike
