Hello Mr. Finger,
I don't know if this is the right way for contacting you but I couldn't
find the other way.
Firstly, I want to say that I am student at School of electrical
Engineering in Belgrade and I am working on some embedded project where I tried
to use you RTL8187 Linux driver to communicate with PIC32 microcontroller over USB.
I would appreciate any help with my problem. If you could spare some time
to read this it would be great. I have several questions. Initialization worked
fine I think (I get ACK packets), but when I try to finally send IN packet to
endpoint 0x81 I get NAK packets all the time!
I checked code in microcontroller several times and, of course, maybe error
could be somewhere in initialization, but would that block my IN packets to
device? I know that PIC32 cannot work in high-speed mode, only in full-speed,
but in the datasheet for this dongle it says it can work in full-speed. So I
want to know does USB card set its speed to full-speed automatically?
I think my understanding of driver code is good so you can give me some
general guidelines regarding initialization if you don't want to go to
details.Thank you in advance.
Contacting me is OK, but all communication should also be Cc'd to the
linux-wireless mailing list.
Could you please give me some more details? Is this setup as an ad-hoc wireless
connection? I know that rtl8187 does not work in AP mode, but I'm not sure about
ad-hoc mode, and I am unable to test that at the moment.
Which device are you using - RTL8187L, or RTL8187B? The USB ID should tell that.
Yes, the device will work with USB1.1 hardware, and it might even work with
USB1.0, but I have never tested that.
