Hello!
У меня возникли проблемы при попытке использовать "переходник"
USB-serial с помощью драйвера pl2303 (написанного именно для этого
устройства) из ядра 2.4.7-alt2-up (с 2.4.5 и 2.4.6 то же самое). Может у
кого-нибудь есть идеи по поводу того, как пытаться исправить?
Вот мое письмо автору драйвера, которое должно все разъяснить.
Best regards,
Ivan Z.

Subject: usb-serial driver pl2303.c crashes
Greg,
As you can guess, I have got a Prolific USB-to-serial converter
(PL2303), and am trying now to use it.
Here is the scheme of what I am doing:
I boot up my system with a 2.4.7 kernel, usb-ohci is loaded.
Then I issue the command modprobe pl2303 debug=1. Connect the converter
to one of the USB holes and the other end to a serial port of the same
computer (ttyS1). It is detected, and assigned to /dev/usb/ttyUSB0.
Then I try to send a byte ('a') through the conveter., so I run
$ cat /dev/ttyS1
and on another console
$ echo a > /dev/usb/ttyUSB0
At this moment something horrible happens -- I attach the logs that
might be useful. I'm not a kernel hacker, but I'd like to get this
driver working, and I'm ready to test it. Do you have any suggestions
what to do?
By the way, I tried to use it in other ways and in other configurations,
for example on a computer with Intel's USB (with usb-uhci module), and
with other kernels (2.4.5 and 2.4.6).
When I try to do the same the second time (echo a > /dev/usb/ttyUSB0),
it behaves differently: some debug messages are printed out, but the
byte doesn't appear to go through and the echo process doesn't exit --
so I press Ctrl-C to stop it. So the second time it doesn't work either.
The log for the second attempt is attached as well.
The test of writing in other direction (from ttyS1) results in a
complete crash of the system (it says something about a fault in an
interrupt handler).
So that's it. I would be glad to hear any advice from you.
Best reagrds,
