I have installed followed by "how to"(linuxquestions.org/questions/answers.php?action=viewarticle&artid=239), but it seems that my ma111 doesn't work, in /var/log/message it says:no modules for usb.and when I reinserted the adapter,the linux system didn't work too!!what's wrong?please help me!thanks!

by the way:I used linux-2.6.3

You might want to post the complete message, but from this it looks like your kernel doesn't support USB. I know you posted the kernel version, but is this a kernel that came with your distro or is it a custom kernel? Also, what distro are you using?

thanks for your reply!what's distro?sorry I don't known this,I am a newbie to linux.these are some infomations:
OS:Red Hat Linux 9.0(linux-2.4.20 | linux-2.6.3(new compiled))
Windows XP professional
I have downloaded and installed "linux-wlan-ng-0.2.1-pre20.tar" in linux-2.6.3,
but it seemed not work.and what's more,when I inserted the "MA111" (or other
usb wireless adapter(atmel)),the system halted!!!but it had nothing wrong when I
inserted my usb disk!and I looked in the /var/log/message,it said:no modules for
usb devices(0x0846:0x4110).thanks for your help!

You need to provide more details than "it seemed not work". Please post the error messages you are seeing. If the linux-wlan-ng compile and install aren't working, then nothing you do afterwards will either.

please see this thread for where your problem might come from (you have to compile the 2.6 kernel completly before you can compile the linux-wlan-ng driver).

Good luck !

thanks for your reply!I have compiled and installed the linux-wlan-ng successfully,but when I insert the MA111, in linux-2.4.20-8,these are some infomations in /var/log/messages:
Sep 22 10:46:56 loacalhost kernel:hub.c:new USB device 00:07.2-2,assigned address 2
Sep 22 10:46:56 loacalhost kernel:usb.c:USB device 2 (vend/prod 0x846/ox4110) is not claimed by any active driver.
Sep 22 10:46:56 loacalhost /etc/hotplug/usb.agent:... no modules for USB product 846/4110/132
please help me more,thanks

thank you!I have compiled linux-2.6.3,but when it restarted,the usb mouse and usb keyboard didin't work!what was the matter?I have enabled anything of usb when configured.by the way,did MA111 can work in red hat linux-2.4.18 or 2.4.20 or only in 2.6?

The MA111 USB adapter works fine with both the linux-2.4 kernel and the linux-2.6 kernel. I've used it with Redhat 9, Fedora Core 1 and Fedora Core 2 stock kernels.
If everything worked fine with the stock kernel, be sure to use the kernel config files shipped with the Redhat/Fedora kernel sources and not a home made one, it might save you a lot of troubleshooting (see the thread mentionned in my previous post).
If USB doesn't work with the stock kernels, you might want to post in the hardware forum to get some advice before going any further with the MA111 installation.

thank you!I am really disapointed,I tried many times,but failed.How did you make it work in red hat linux 9.0?please show me in detail,I will thank you very much!help me!would you please reply me?or send me an email:jarrywhu@yahoo.com.cn Thank you very much!

any more help?

Just follow the procedure in the linux-wlan-ng README file, stop when you've got an error and report the error here.
I won't write a complete tutorial (you've got pretty much all you need in the thread I mentionned before and again I emphasize that if you're running a 2.6 kernel, you have to do a complete compile before generating the module), as I don't have time do to a complete Kernel-compiling 101 course ;-)
With Redhat 9 (linux 2.4) everything worked out of the box (assuming you installed the kernel sources and developpement tools) : make config, make all, make install, modprobe prism2usb, ifconfig wlan0 etc...

I'm running Mandrake 10.1 which uses the 2.6 kernel and I get a bunch of errors when I do the make all command with the linux-wlan driver. I have the MA111 as well. I do not have a /etc/wlan folder.

There's another thread that touches on the error I get but doesn't have a fix for it.

any way,thank you very much!
