I'm facing an USB read/write issue on omap3730
Kernel version: linux-2.6.32
Processor- omap3730
Transceiver used - USB3320

After booting of the board, led on USB3320 PHY is glowing,once I insert USB device and transfer data to USB device I face below issue and the port goes to off mode(led on phy also stops glowing)
Can anyone please help me in this issue.
Thanks in advance.

Seems like you're drawing too much current from the port. So the port switches off, and disk access never likes to have the device it's talking to vanish - hence the string of nonsense.
