driver for OTI 006858 USB-to-serial IC has errors

[PowerUser]

I own USB to serial cable (for cell phone) based on OTI 006858 IC.It not seems to work.No ttyUSB? device created when I attach this cable and it not seems to operate properly.

Tested undeer Ubuntu Fiesty 7.0.4 x64 (both Alpha and daily build from 3.1.2007).Both have same behavior.

When attaching device:
[ 2246.275535] usb 1-6: new full speed USB device using ohci_hcd and address 4
[ 2246.377827] usb 1-6: configuration #1 chosen from 1 choice

Thanks for your bug report. Is there a kernel module loaded for this device when you insert it? You could run 'lsmod' before and after inserting the device and checking to see if there is a difference between the two outputs. The command 'dmesg' after inserting the device could be also informative.

[Brian Murray (brian-murray)]

We are closing this bug report as it lacks the information, described in the previous comments, we need to investigate the problem further. However, please reopen it if you can give us the missing information and feel free to submit bug reports in the future.

theri is no mathing module. but it works adter addin patch to kernel. this path is located http://www.gnokii.org/download/gnokii/patches/

[Marco Costantini (costanti)]

I have this cable, and I had the same problem with the old kernels. It seems that it requires kernel 2.6.24 (as in Ubuntu 8.04). With this kernel, the /dev/ttyUSB0 device is created. However, the connection to the mobile phone still doesn't work. I get a lot of the dmesg message
[ 6264.856587] oti6858_read_int_callback(port = 0, status = 0)

[Raphaël Doursenaud (rdoursenaud)]

Bug confirmed on released Hardy 8.04 with kernel 2.6.24-16-generic.
oti6858 module loads successfully but trying to access the device gives a bunch of :
"oti6858_read_int_callback(port = 0, status = 0)"
messages and some :
"oti6858_chars_in_buffer(port = 0)
 oti6858_write_room(port = 0)"
until you kill the application accessing it which gives :
"oti6858_close(port = 0)
 oti6858_close(): entering wait loop
 oti6858_close(): after wait loop
 oti6858_read_int_callback(port = 0, status = 0)
 oti6858_close(): after schedule_timeout_interruptible()
 oti6858_close(): shutting down urbs
 oti6858_read_int_callback(port = 0, status = -2)
 oti6858_read_int_callback(): urb shutting down with status: -2"

This bug does not meet the criteria for a stable release update and is being marked as Won't Fix for kernel version 2.6.22. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates .

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Marco Costantini (costanti)]

This bug is still present in Alpha5 for Intrepid Ibex 8.10, kernel 2.6.27.2.

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

There has been no upstream activity in this driver since Oct 2008. Closing for Jaunty.

[Marco Costantini (costanti)]

This bug is still present in jaunty with kernel 2.6.28. Here is more information.

[Marco Costantini (costanti)]

With the kernel 2.6.28 and everything else as in my previous comment, all the programs (wammu, xgnokii, kppp, minicom, kmobiletools, scmxx) trying to access /dev/ttyUSB0 report timeout.

The various dmesg messages, such as
[ 6264.856587] oti6858_read_int_callback(port = 0, status = 0)
reported with previous kernels are no more present: the dmesg message are only when inserting the cable, as in my previous comment.

[Andy Whitcroft (apw)]

Could you include an strace of one application trying to open this device and timing out. Thanks!

Marco,
     This bug does not meet the criteria for a stable release update and is being marked as Won't Fix for kernel version 2.6.22. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates .

Can you confirm this issue exists with the most recent Karmic Koala 9.10 Alpha release? ISO CD images are available at http://cdimage.ubuntu.com/releases/karmic/ . If the issue remains with Karmic it would be great to then also test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .

Thanks in advance.

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future.

[rusivi2 (rusivi2-deactivatedaccount)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. My apologies as I should not have marked this Invalid. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Maverick Meerkat. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

Hi there

We'd like to figure out what's causing this bug for you, but we haven't heard back from you in a while. Could you please provide the requested information? Thanks!

[PowerUser (i-am-sergey)]

This bug has been about completely missing OTI 6858 device driver. Right now this driver presents in supplied kernel:
[ 2337.360240] oti6858 4-2:1.0: oti6858 converter detected
[ 2337.360327] usb 4-2: oti6858 converter now attached to ttyUSB0
[ 2337.360342] usbcore: registered new interface driver oti6858

So I'm about to close this bug. If someone encounters some other issues with this driver, I believe they should create separate bug since this bug had nothing to do with other issues.

Marking it as "fix released" because driver in question presents in current kernels.
