/proc/bus/usb/devices from NOT working 2.6.24
I have a quite similar problem with an Edgeport 4S or 8S device (which also use io_ti module): Works fine with 2.6.23.17 kernel Doesn't work with 2.6.24 and later kernels (the device is not detected and appears at "Unknown Device" in usbview) I have tested with 2.6.25-rc8 too and the problem still remains the same. As a side note : this bug seems very similar to bug number 10118 where "akpm" states that something has probably been broken in USB core. Below is a diff between /proc/bus/usb/devices from 2.6.23.17 and 2.6.24 (don't know if it matters, but ProdID has changed from 0x02c2 to 0x288) -T: Bus=03 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 10 Spd=12 MxCh= 2 +T: Bus=03 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 4 Spd=12 MxCh= 1 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 -P: Vendor=1608 ProdID=02c2 Rev= 1.51 +P: Vendor=1608 ProdID=0288 Rev= 1.51 C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA I:* If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)

.config for the 2.6.24.5 kernel
The .config file used to build the kernel.
(I figured out how to make an attachment. *duh*)

Output of lsmod with Edgeport/4 plugged in
what other kernel modules are loaded when there's a problem, fwiw.
Running 2.6.24.5 kernel build with the previously attached .config.
This should all be fixed in the latest 2.6.25 kernel release, right? Can you test that to verify it? Yeah. Sorry I forgot to reply here. Just tested the 2.6.25.1 Kernel a few days ago and every thing went fine! Thank you for fixing the problem! Thanks for verifying, am closing this out now. |
Latest working kernel version: 2.6.23.17 Earliest failing kernel version: 2.6.24 Distribution: Gentoo Linux with original sources from Kernel.org Problem Description: It took my a whole day to find out, why my Edgeport/1 did not work with the latest stable Kernel (2.6.24.4). Whenever i attached the device dmesg produced the following messages: ----- usb 2-1: new full speed USB device using uhci_hcd and address 8 usb 2-1: configuration #1 chosen from 1 choice usbcore: registered new interface driver usbserial drivers/usb/serial/usb-serial.c: USB Serial Driver core drivers/usb/serial/usb-serial.c: USB Serial support registered for Edgeport TI 1 port adapter drivers/usb/serial/usb-serial.c: USB Serial support registered for Edgeport TI 2 port adapter io_ti: probe of 2-1:1.0 failed with error -5 ----- I was sure it worked lately, so i downgraded to an older (2.6.22.19) Kernel and voila... there everything worked. ----- usb 2-1: new full speed USB device using uhci_hcd and address 7 usb 2-1: configuration #1 chosen from 1 choice io_ti 2-1:1.0: Edgeport TI 1 port adapter converter detected usb 2-1: Edgeport TI 1 port adapter converter now attached to ttyUSB0 ----- After Downloading some Kernel Versions i found out the following: -> When i try to compile 2.6.24.4 and attach the device i get "error -5". -> when i copy the 2.6.22.19 usb-serial.c over the 2.6.24.4 usb-serial.c file the attached Edgeport/1 is getting recognized and /dev/ttyUSB0 is created. -> when i copy the 2.6.23 usb-serial.c over the 2.6.24.4 usb-serial.c file the attached Edgeport/1 is getting recognized and /dev/ttyUSB0 is created. -> when i copy the 2.6.24 usb-serial.c over the 2.6.24.4 usb-serial.c file the attached Edgeport/1 produces the "error -5" Looks like the changes made between 2.6.23 and 2.6.24 in usb-serial.c prevent io_ti from working correctly. Steps to reproduce: Take Kernel 2.6.24 and choose Device Drivers ---> [*] USB support ---> USB Serial Converter support ---> <M> USB Serial Converter support <M> USB Inside Out Edgeport Serial Driver (TI devices) Attach Edgeport/1 and when the modules are loaded you get: io_ti: probe of 2-1:1.0 failed with error -5 From Kernel 2.6.23.17 copy drivers/usb/serial/usb-serial.ch over the file in the 2.6.24 directory, recompile and the Edgeport/1 Driver loads and creates /dev/ttyUSB0 (and beside that, also works perfectly!).
