The same hardware hotplugs in 2.4, In 2.6.1-rc1 if I try to manually load the cdc-acm module I get:
[EMAIL PROTECTED] class]# /sbin/insmod cdc-acm.ko Error inserting 'cdc-acm.ko': -1 Unknown symbol in module
What symbol did syslog report was "unknown"?
... cdc_acm: disagrees about version of symbol usb_alloc_urb cdc_acm: Unknown symbol usb_alloc_urb cdc_acm: disagrees about version of symbol usb_free_urb cdc_acm: Unknown symbol usb_free_urb cdc_acm: disagrees about version of symbol usb_interface_claimed cdc_acm: Unknown symbol usb_interface_claimed
Since "usbaudio" loaded successfully, it's clear those symbols exist ... but that, as these messages say, you've got symbol version mismatch problem. As if you rebuilt the CDC ACM driver against a different kernel.
Try rebuilding your kernel, possibly without module versioning.
