insmod error

[oarecare]

when trying to install usb devices (usb to serial, bluetooth etc), i get the following errors:
insmod: unresolved symbol __up
insmod: unresolved symbol __down

is there any way of getting read of these errors and installing the modules?

i'm using openwrt on wl-700gE


Edit: did a 'ipkg install kmod-usb-serial' and got rid of that error. Now, whenever i try to read from or write to the port the router hangs. Any suggestions?

Are you using one of the images from http://wl700g.homelinux.net/drupal/ ?
or your own build? Perhaps you didn't compile OpenWrt with usb support? :)

am using kamikaze, installed all the ipkgs that looked relevant... and it got fixed (no idea which one did the trick)
now i am in another hassle:
echo 'test' > /dev/usb/tts/0 works... but cat < /dev/usb/tts/0 does not.
i'm almost sure there is a port setting somewhere causing all the headache

stty -F /dev/usb/tts/0
returns

speed 57600 baud; line = 0;
-brkint ixoff -imaxbel

tried none, rts/cts, ixon/ixoff...

adapter is ok, tested on windows (tried both ftdi ft232 and prolific pl2303)
