https://bugzilla.kernel.org/show_bug.cgi?id=60824 --- Comment #216 from pverda@xxxxxxxx --- Hans de Goede: I have done some testing. If I use the current module the well known errors are produced in both ways. That is with and without the module options. If I use the modified btusb module with all the quirks except the Barrot quirk the dongle functions without any error if the module options are there. If I use it without the module options I can't connect to the dongle. I also have lots of command timeout errors in my log file. Swyter: I do not have the full kernel source tree on my system. I only have the kernel-devel package and this is limited in its capabilities. About the dongle: The dongle is a rectangular one with the print "CSR 4.0" on it. I bought it a couple of years ago on aliexpress. It has the peculiarity that is support aptx. -- You may reply to this email to add a comment.
