Public bug reported:
I am using a Dell Inspiron 1525 and I cannot copy large amounts of files
from my USB card since it does it at a very slow rate (around 300kb/s).
I tested the SD card in another computer and it works properly. It also
works without problems in Windows on this machine, so the problem must
be here.
Please, let me know what info would be helpful, since I have no idea
where to start.
As an aside information: the wireless connection is also working too
slow in this machine, I don't know whether it could be a related
problem.
