Both of them, i have a unpacked kernel on the drive and would do a copy
and paste into another directory of the same drive, transfer speeds of
50 MB/sec are good through about half way through the transfer event
then a hang occurs from this point on transfer speeds drop to 20MB/sec
and then slowly ramp down to less than 5MB/sec at the end of the file
transfer. this is with both uas and usb-storage.

I have some traces, there very large and the mailing list filter will
reject them. so i will send them directly.
