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).Now pressing "Enter" as requested reads data from usb (controll light flickers), saying: "System: debian-installer" Label: bootable drive Date: 20031226 Loading............"
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.
... ok, just verified, light is only on on lager data transfers.
some speeds: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.
[EMAIL PROTECTED]:~# time cat /mnt/stick/netinst.iso >/dev/nullcatting 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?
