I am stuck with a 2014.04-r0 u-boot source, and have an issue where USB
flash sticks 4 GB and greater cannot be read by u-boot - the device is not
detected when "usb reset" is run.
USB hub found
0 Storage Device(s) found
This platform is based on an am335x SOM, and the manufacturer has not
updated any drivers for a long while...
The device can be read by the Linux running on the platform without issue
"ID 058f:6387 Alcor Micro Corp. Flash Drive"
Can anyone suggest if there is a way (without upgrading) to resolve this,
or just mark it as obsolete (and that is the way it stays)
Thanks
Floyd Brown

The am335x chip is well supported in mainline U-Boot, you should have
some luck just upgrading.
