[sane-devel] Brother DCP7030: invalid argument with Sane 1.0.14-9

[Pawel Chojnacki]

Hello again,

I have an update: scanner works perfectly with Brother drivers only with
USB2.0 (haven't checked 1.0) ports, and doesn't want to start using my 3.0
or eSATA ones. It's a serious problem for me, as I don't have any other
data ports in my notebook.

Do you think it's a sane-, or a Brother- problem?

Thanks,

Pawel Chojnacki
