I have a question, I use USB-serial interface like a lot of other drivers under drivers/usb/serial/, my question is when I have two equal devices connected to the USB bus, that are using usb-serial, in memory are there two copies of the driver or just one?. Because I think that my problems could be happening because I have only one driver on memory. If it is the case, then the bug is not worth to be corrected, because who would connect to Bluetooth devices to a pc and send data from one to the other? Only developers and testers would get profit of this. Regards, Manuel
