You might be able to improve things by changing the timing and throughput.  
Here's how:  In drivers/usb/storage/scsiglue.c you'll find a line that 
defines max_sectors as 240, something like

        .max_sectors =          240,

Try decreasing that value to 128 or maybe even smaller.  That might very 
well improve your transfers.
