[Voyage-linux] Re: more on usb and latest voyage 0.2pre4 release

Hi Mark,

Forward voyage-related question to voyage-linux to capture more attention

Can you use install stock 2.6.8 kernel in your debian machine?  I
would like to know if it is driver problem or 2.6.15-voyage specific
problem.

If you can also supply a full lsmod and dmesg output (from voyage
kernel and stock 2.4.27), I am able to do the analysis for you.

My past experience told me that:
- It may relate to hotplug that loads a wrong USB hub driver.
- It may relate to kernel configuration issue.  If you can run stock
2.6.8 kernel with your driver successfully, it can be confirmed.
