Hello all,
since I updated from Opensuse 10.3 to 11.1 the writing speed to my USB sticks dropped strongly. I have a “no name” stick of around 900MB and a 8GB “Sony Microvault”. Previously I could write to the Sony at about 4 MB/s and read with 15 MB/s. Reading is still OK, but the writing slows down continuously from some MB/s to about 0.5 MB/s with larger files (>100 MB). Similar results with the “no name” stick.
Does somebody know the solution? Or are there settings with which I could play around to solve this problem?
This is the output of “lsusb -t” (with the Sony stick mounted):
/: Bus 05.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/8p, 480M
|__ Port 6: Dev 6, If 0, Class=stor., Driver=usb-storage, 480M

And of “mount”:

Thank you in advance!
