You should use Linux 5.17.1.Īnyone who needs a patch for linux 5.15.x LTS series, can use this patch. Linux 5.17 still needs the v4 patches to be applied manually. dmesg report of second dongle: usb 1-4: USB disconnect, device number 4 I plug another dongle which has exactly the same housing (CSR 4.0 on both), and it works.
I updated to linux 5.17, and my dongle is still not working :(( dmesg report: usb 1-4: new full-speed USB device number 4 using xhci_hcd usb 1-4: new full-speed USB device number 5 using xhci_hcd I plug another dongle which has exactly the same cover (CSR 4.0 on both), and it works.ĭmesg report of second dongle: usb 1-4: USB disconnect, device number 4 Bluetooth: hci0: Opcode 0x c01 failed: -110 Bluetooth: hci0: command 0x0c01 tx timeout Bluetooth: BNEP socket layer initialized Bluetooth: BNEP filters: protocol multicast Bluetooth: BNEP (Ethernet Emulation) ver 1.3 Bluetooth: hci0: CSR: Couldn't suspend the device for our Barrot 8041a02 receive-issue workaround

P.S.: How did you get the kernel guys to respond to you? I have recently made my first kernel patch that even made it into their so far, no one has actually made a single comment to me about it.
#Csr 41b14 driver windows#
What's worse, trying them in a windows virtual machine actually worked :( Anyways, you did it! I was so happy that I thought I just had to read through the git log and find out who fixie wixied this fucksy upsy! However, none seemed to cover this specific hardware version. I have read about how support for these devices is known problem and there are even blog articles with kernel patches. I knew it was a gamble from the beginning. Never read through this whole long thread, but thanks so much senpai! I just updated to linux 5.17 and my dongle works now! I bought a metric ton of them (like 8 or whatever) on aliexpress because they were like 2€s and I keep losing my normal 10€ dongles.
