Dear experts,
we are trying to make an demo product for one of our prospective
customers. They wish a WindowsCE based network device. So we started
from an Enterprise Web pad, Platform Builder 5.0, and a LEX board (x86
like, 3 soldered in RTL8139 adapters).
The debug image was built, just by adding a network capabilities of one
RTL8139 adapter from PB5 catalog ( no such provision like 'Second RTL'
is available in PB5). Assuming that multiple driver instances will be
created at run time.
When only one network adapter is enabled by jumpers, debugger runs and
image is more or less stable.
However, if 2 network adapters are enabled by jumpers, the kernel
debugger only progresses to a certain point where image always hangs.
The last debugger output is below :

and that's it. No clean rebuild helps or restarting of PB, rebooting
the desktop machine, etc.
I wonder how the enabling the second adapter can cause the hang on the
usbd module ? Or, what special settings have to be implemented in
platform to support 2 identical network adapters in Windows CE image ?
Sincerely
Sergei
