That's all, this dots keep on filling up the screen, aprox. one per
second. I had this run for more than an hour, and i don't belive this is
correct. Even if it would unpack the iso in it and install whole base
system....

Tried that with same results on 2 old systems (workstation with
p450/192mb and laptop with cel400/192mb). A third system (xp2600) faild
accessing usb (filed a bug report on that).

So, what is wrong here? how to go on?

The weird thing about this is it should only print one dot each second
that some data was retreived from the usb device. If the usb device were
stalling, there should be no dots; so it must be getting _some_ data
from the device.

In general my usb device has a light blinking when data is transfere from or to it. But it only blinks a little at beginnig of usb access, during "dotting" it doesn't. More, when disconnecting it, though i get a "USB disconnect" message dots still apperar as before (currently i see 10 lines, each 80 char), still running (disconnected).

... ok, just verified, light is only on on lager data transfers.

You might want to either install linux by some other means on one of the
machines, or try the usb device on some other machine running linux, and
see if there are general problems reading a lot of data off of it at
once. Just catting the initrd from the disk to /dev/null would be a good
test.

some speeds:

root@silver:~# time cat /mnt/stick/netinst.iso >/dev/null
real    0m0.610s

user    0m0.000s

sys     0m0.500s

root@silver:~# time cat /mnt/stick/initrd.gz >/dev/null
real    0m0.005s

user    0m0.000s

sys     0m0.010s

catting initrd doesn't blink at all, but wait... netinst.iso ought to be around 120 mb, so 0.6s real time is quite fast to read (usb1.1), isn't it?

So, reading from usb is not the issue?
