Bug#704242: Driver for PL-2303 HX not working

Then the problem is most likely not in the driver as the characters are
being read back in the log you provided.
Stop - it's really possible that i send not enough bytes.
Sometimes up to 6 Bytes will come back.
This time i send this string (3.2.0):
"1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890\n"
I get back the first 3 Bytes of it.
Log is attached.
Was it really the same log? In the log below there is an error reported
but it looks like no data at all is returned:
No - this are of course different tests and different logs.
Sorry - it's possible that there where no bytes read back in this particular test.
I added exact output to my script now.
Here are two additional tests with 50 bytes (3.2.0).
In sendtest50get2.log i definitely read 2 Bytes back.
[ 1443.122568] /build/buildd-linux_3.2.23-1-amd64-zj7gxu/linux-3.2.23/drivers/usb/serial/generic.c: usb_serial_generic_read_bulk_callback - nonzero read bulk status received: -84
Either way, the error is EILSEQ (-84) which usually indicates hardware
problems.
Maybe this time not plugged in perfectly.
This cheap connectors are sometimes not reliable.
It's the same connecting an external harddisk - sometimes you have a bad connection.
There are 2 beasty questions left:
1. Why it works with PL2303H ?
Different device, different hardware.
But it's the same driver or not?
2. Why i receive sometimes the first bytes?
Your particular device could be flakey and sometimes you're able to
read a few bytes.
Sorry - i don't think so.
1. It works perfect with kernel 2.6.32
2. It works perfect using windows with the driver from Profilic
3. I have 2 devices of this type and the behaviour is exact the same
If you still want to pursue this, you should try to reproduce the error
on a v3.8 kernel (look in the logs for errors from
usb_serial_generic_read_bulk_callback). Then you could try to reduce the
bulk-in and out buffer sizes in the driver (simply comment out those
fields in the pl2303_device struct) and perhaps also to reduce the
number of read and write urbs (I can tell you how later).
I will try to do this - but it takes time ...
