Title: Bluetooth Driver Problems
Post by: liberated on March 09, 2007, 04:04:05 am

My Ambicom BT card (LSE039) won't work. Cardctl identifies the card OK. The problem is with the driver. Here's the errors you get from 'modprobe bluecard_cs':

/lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: /lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: unresolved symbol hci_register_dev
/lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: /lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: unresolved symbol hci_recv_frame
/lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: /lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: unresolved symbol hci_unregister_dev
/lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: insmod /lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o failed
/lib/modules/2.4.20/kernel/drivers/bluetooth/bluecard_cs.o: Can't locate module 2

It looks to me like the driver is all broken, is there a fix?

I found the problem. The kernel is broken. The /lib/modules/2.4.20/kernel/net directory is missing (or if it was empty, without subdirectories like bluetooth) and modules.dep is missing all dependencies for these modules.

Luckily the kernel contained in the hdimage is complete, thus i fixed this by copying the said subfolders and modules.dep from /media/fakeroot/ to the rom root (/).

this is fixed in the latest pdaXii13 Akita build 5.3.2 which was uploaded about an hour ago

the net directory actually exists, but is in the wrong location under /lib/modules
there are a few enhancements in this new version, the most noticable will be faster rotation and resume....

the spitz version is still being uploaded and once it is done, there will be an announcement...
