So, I've been working on getting this driver working with my Netgear
EA-101 but I've run into some problems.
Before I start, I'm curious what tab spacing the driver was coded with? Looks
like it's twice the size of my tabs :)
The first problem was the superfluous spin_lock_init calls to nonexistant
variables. Removing them fixed that. I'm kinda surprised this one wasn't
caught since the driver won't even compile.
The second problem I've run into was a small bug in my UHCI driver
regarding SPD being turned off on control transfers. Fixed that.
The first kaweth_read_configuration gets called, and we get a short packet
back. Since SPD is not set, it retries the IN token a couple of times. A
couple of them receive no reply. Eventually the transfer times out.
Then the control pipe gets unhalted, those transactions work fine, but then
when the code tries to download the firmware, it doesn't respond to the
SETUP packet.
If I completely remove the first kaweth_read_configuration, everything works
fine.
I get the same exact problem with usb-uhci, so I don't think it's something
with my driver.
Has anyone gotten this working with the 0.2 driver?
