I'm experiencing an issue when loading a generic distro initramfs on trimslice-pro (with ssd using ehci) with the default value of 65535 for USB_MAX_XFER_BLK EHCI timed out on TD - token=0x80008d80
As adviced by Marek on IRC, using a lower value for USB_MAX_XFER_BLK allows to load the file
Tested values on tegra20-trimslice: 4095 ok 32767 ok 32768 timeout 36864 timeout 40960 timeout 49150 timeout
Tested on current u-boot master
