Hi,
My T42 ships with 2 hi-speed USB ports. They're managed boy ehci-hcd
kernel modules, the only ones loaded into memory.
Anyway, I get super slow data transfer rates and I can't understand
why:
It takes 14 min (!!) to transfer 57MB to a USB pendrive (which is also
hi-speed USB):
$ du -h LosSecretos-UnayMilVeces
57M LosSecretos-UnayMilVeces
$ time cp -r LosSecretos-UnayMilVeces/ /mnt/iaudio/music/
real 14m12.669s
user 0m0.000s
sys 0m0.812s
What transfer speeds do you get ? What is the reason it goes sooooo
slow ????
