Good day.
A while ago, my noname USB Bluetooth adapter stopped working, with from
that point on only "Bluetooth: hci0 command tx timeout" appearing in the
kernel messages.
I just now got around to looking at it and bisected this to commit
eead27da60df80a112d1ac3ea482226e9794c26b:

Author: Andre Guedes <andre.guedes@openbossa.org>

Bluetooth: Add lmp_host_le_capable() macro
Since we have the extended LMP features properly implemented, we
should check the LMP_HOST_LE bit to know if the host supports LE.

while that commit cannot be reverted outright due to dependencies,
reverting it functionally fixes things for me. That is, Bluetooth works
again after applying (to linux-3.1.6):

It seems that my adapter wasn't ready for the change. It is a:
002 Device 002: ID 1131:1004 Integrated System Solution Corp. Bluetooth
Device
If more specific information is wanted (to add adapter-specific quirk
handling, perhaps?) please be verbose on how to obtain it. I don't know
anything about Bluetooth

Load Bluetooth module. 3.

Can you try with the following diff (use the dynamic debug that Andre > told you) Attached. The result is "features: 0xff". I suppose that (should) mean(s) "all features"; if that's not actually a valid possibility due, perhaps, to undefined or mutually exclusive bits then maybe it's an option to take 0xff to mean that the adapter doesn't in fact support any of them? > Also the output of hcidump would nice. If the below (which is what hcidump spit back at me at some as far as I could determine random moment) is not what you wanted, I believe you will need to specify which action to take while monitoring things with hcidump. ============== HCI sniffer - Bluetooth packet analyzer ver 2.1 device: hci0 snap_len: 1028 filter: 0xffffffff < HCI Command: Reset (0x03|0x0003) plen 0 > HCI Event: Command Complete (0x0e) plen 4 Reset (0x03|0x0003) ncmd 1 status 0x00 < HCI Command: Read Local Supported Features (0x04|0x0003) plen 0 > HCI Event: Command Complete (0x0e) plen 12 Read Local Supported Features (0x04|0x0003) ncmd 1 status 0x00 Features: 0xff 0xfe 0xff 0x7e 0x98 0x19 0x00 0x80 < HCI Command: Read Local Version Information (0x04|0x0001) plen 0 > HCI Event: Command Complete (0x0e) plen 12 Read Local Version Information (0x04|0x0001) ncmd 1 status 0x00 HCI Version: 2.0 (0x3) HCI Revision: 0x2da LMP Version: 2.0 (0x3) LMP Subversion: 0x2da Manufacturer: Integrated System Solution Corp.

It worked well upto and including 2.6.29 though. This would seem to be the kind of thing other subsystems use quirk handling for.

I think this patch can do handling, let's see what others think. Gustavo --- Author: Gustavo F. Padovan <padovan@profusion.mobi> Date: Wed Dec 28 13:40:02 2011 -0200 Bluetooth: Fix lmp_host_le_capable() check for broken devices Some dongles reports a wrong Local Extended Features leading the kernel think that dongle support LE while it don't. The fix here is just rely on a bit in Local Features (LE Capable) to tell us if the device really supports LE. LE Host Capable is the only bit used from Local Extended Features in our kernel.

Sure, we will, but I don't see us using another bit of extfeatures in the near future (after the next Core Spec release maybe) and I don't wanna got that far in this fix right now.

So besides switching LE on when requesting page 0, you will also switch it off when requesting any other page and it accidentally returns 0x00 since we unconditionally overwrite it.

By the way, while the bluetooth (2.0) spec seems to consist of a 1230 page document that I am most certainly not going to study ... ... I couldn't help noticing that the HCI_Read_Local_Extended_Features command is in fact specified to return "The highest features page number which contains non-zero bits for the local device", and if I look at the above, it seems to indeed return max=0.

However the expected result from the dongle would be an error code and not just returning page 0 instead. And the max value just tells you about the max page value.

Okay. Just as an additional data point: I came across the HCI_Read_Local_Supported_Commands command in the spec a few pages up and quickly verified that the adapter doesn't in fact deny support for the HCI_Read_Local_Extended_Features command. That is, after applying the below, I do get: hci_cc_read_local_commands:hci0 status 0x0 hci_cc_read_local_commands:hci0 commands[14] 0xe8 which does claim support for the command (bit 6 of commands[14]). Thought I'd check since if it hadn't, that would imply a certain fix but that can't be used then. I'll stand by to test whatever final solution is arrived at. (although I don't personally care, linux 3.0.y and 3.1.y may want it as well at that point I guess).
