[sane-devel] problems Plustek backend with Canon Lide-30

[Gerhard Jaeger]

Hi Peter,

sorry to hear that, but in the end that's what I've expected. It seems, that
the 2.6 kernels still have enough USB trouble. You might try 2.6.8-rc3...
I noticed, that at least 2.6.5 has problems in detecting some chips and so
on - 2.6.7 and up has some trouble with ehci - not very satisfying :(
I do still a lot of work on my 2.4.27 based box and also the tests before
releasing.
but thanx for the feedback and good luck in finding the probs, at least
the guys answering on the usb-devel list seem to be very cooperative

Ciao,
  Gerhard
