Since 2.6.0-test7-bk1, the kernel fails to recognize my USB ISDN TA and load the ACM driver. When the ACM driver is compiled in the kernel, the oops message shows up at boot, when compiled as a module, it shows up when I disconnect the device. Either way, when connected the device does not work. In the e-mail I include the oops file processed by ksymoops and my system information.
If that's the "Intracom S.A. NetMod USB" from your usb/devices file, the "not recognize" is strange ... it's only got the one config, it should "just work".
The oops looks like it was trying to printk() some message, with a bit less success than below, in the same case: trying to claim the second interface.
The CDC-ACM probe() logic needs to be replaced, but I didn't think it could fail as that.
And I had this message at boot time (on kernels < 2.6.0-test7-bk1) :
hub 2-0:1.0: new USB device on port 1, assigned address 2 drivers/usb/class/cdc-acm.c: ttyACM0: USB ACM device drivers/usb/core/usb.c: acm driver booted <NULL> off interface dfafa740 acm: probe of 2-1:1.1 failed with error -5
This doesn't make a lot of sense unless your kernel memory was first corrupted by something.
