[Taipan] Failed to read firmware version

[Fragan]

Hello,

Thanks to you to provide Razer mice support for Linux.

Today, I have installed the latest version of razercfg on Ubuntu 13.10 (3.11.0-12-generic x86_64) for my Razer Taipan.

The installation went smoothly, but when I start razerd I have the following error message:

$ sudo razerd
Razer device service daemon
librazer: No config file /etc/razer.conf present. Ignoring.
librazer: razer-taipan: Failed to read firmware version

I would be happy to provide you any helping information.

Regards, Fragan.

Hello, I have Taipan mouse and it works for me. I think that there could be problem with the firmware version. I need more info for fixing it. Can you add line

razer_debug("err=%d, ver=%d\n", err, ver);

to the file hw_taipan.c to the line 166 (function taipan_read_fw_ver)? It should look like this:

... cmd.request = cpu_to_be16(0x8100); err = taipan_send_command(priv, &cmd); ver = be16_to_cpu((be16_t)cmd.value0); razer_debug("err=%d, ver=%d\n", err, ver); // <<-- NEW LINE if (!err && (ver & 0xFF00) != 0) ...

After recompiling run razerd and you should see something like this:

Razer device service daemon [razerd debug]: librazer: err=0, ver=256 <-- NEW LINE [razerd debug]: librazer: profile emulation: Committed active profile ...

Send me please your output. If you can't see new message, you will need to change logging level by parameter -l to 3.

If you want to skip firware version test, you can comment out part of the condition like this:

... ver = be16_to_cpu((be16_t)cmd.value0); razer_debug("err=%d, ver=%d\n", err, ver); if (!err) // <<---- MODIFIED LINE return ver;

But it is only ugly way to find out if firmware version test fix can help.

Hi,

Thank you for help and sorry for the response time, I don't have much time in week.

I have modified the hw_taipan.c file as you mentioned. The razer_debug function shows nothing. After remove the second condition in the if statement, I was able to use the below command:

$ razercfg -V
Mouse:Taipan:USB-001-004:1532-0034-0: Firmware version 0.00

Using razer_error rather than razer_debug, shows me the below lines:

$ sudo razerd
Razer device service daemon
librazer: No config file /etc/razer.conf present. Ignoring.
librazer: err=0, ver=0

Regards, Fragan.

Edit:

For the debug, i forgot to use command to increase logging level (sudo razerd -l 3) This is the 'stacktrace':

$ sudo razerd -l 3
Razer device service daemon
librazer: No config file /etc/razer.conf present. Ignoring.
librazer: err=0, ver=0
[razerd debug]: librazer: profile emulation: Committed active profile
[razerd debug]: librazer: Mouse profile emulation initialized for Mouse:Taipan:USB-001-004:1532-0034-0
[razerd debug]: librazer: Allocated and initialized new mouse "Mouse:Taipan:USB-001-004:1532-0034-0"

Without (ver & 0xFF00) != 0 condition in the if statement, I can configure my Taipan.

Thanks for this workaround.

PS: If you have a fix, I can test it.

What does the debug statement print, if you do not remove the condition?

With the statement if (!err && (ver & 0xFF00) != 0), I have this print:

$ sudo razerd -l 3

librazer: No config file /etc/razer.conf present. Ignoring.
librazer: err=0, ver=0

hm. What if you increase the loop count?

Change the line for (i = 0; i < 5; i++) { to for (i = 0; i < 50; i++) { for example.

I'll change the error condition to be nonfatal for the time being, until a better fix is found.

The same with 200 iterations.

Ok, thanks for testing. I'll apply the workaround. If somebody has a real fix, I'd be happy to apply that, though.

[messani]

I would like to know if there is a way to find out version of the firmware. I am not able to find it. http://www.razerzone.com/gaming-mice/razer-taipan There is a sentence about automatic firmware updates. I updated Razer Synapse, but my mouse is still working. Do you know if the mouse has old or new firmware?

Variable "ver" has value 256 in my case. The question is if the "ver" variable really means firmware version.

We can compare content of the cmd struct. In my case the content is this:

Breakpoint 1, taipan_read_fw_ver (priv=<optimized out>) at /home/tibor/devel/razer/librazer/hw_taipan.c:167
167         if (!err && (ver & 0xFF00) != 0)
(gdb) p cmd
$1 = {
  status = 1 '\001', 
  padding0 = "\000\000\000", 
  command = 2, 
  request = 385, 
  value0 = 1, 
  value1 = 0, 
  padding1 = '\000' <repeats 74 times>, 
  checksum = 131 '\203', 
  padding2 = 0 '\000'
}

I think it would be interesting to know what is in variable "value1". Can you modify line with logging to this:

razer_debug("err=%d, ver=%d, value0=%d, value1=%d\n", err, ver, cmd.value0, cmd.value1);

Closing this issue, as the workaround should do its job until a better solution is found.

[electrojustin]

Hey, I know this is an old thread, but I found this bug and fixed it for my local copy months and months ago and didn't find this thread until just now (I just assumed my mouse was weird), and I see from the commit logs that a proper solution still hasn't been found.

Way back when I was trying to fix this bug in my local copy, I assumed that 0x8100 was the wrong request for getting firmware and tried to find the correct request. A little trial and error revealed that my mouse replies with 50 when the request is changed to 0x8300. The command itself is completely irrelevant apparently, I removed it and nothing bad happened. I don't know if 50 is correct or if there is even any way to check if that's correct, but it seemed plausible-ish and didn't brick my mouse.

[mbuesch]

So do you have an actual patch that improves the situation?

[electrojustin]

I do have a patch. Will it improve the situation? Maybe...I will have to see if I can get a proper version number (possibly using the Razer's own software?) and compare that to 50.

I have mouse that works well with current version. I hope that I will have oportunity to test it this week. I don't have the mouse now.

Thank you.

[Fragan]

Hi,

This patch fix the problem for my mouse.

I have sent a PR https://github.com/mbuesch/razer/pull/23

[messani]

I tested it and it worked for me. Thank you.

[mbuesch]

messani, does it display the correct firmware version for you?

[messani]

Sorry for late reply. I can see firmware version 50 too (in razercfg). But I don't know, how to find out real firmware version (In Razer Synapse). So I don't know if value 50 is correct...

[note89]

So i did my installation with yaourt can i still apply this fix ? cant open the program and have a similar issue as descibed above.
