Error Module Usbserial Is In Use By Option

Sat Nov 03, 2007 12:30 am boran, your device is definitely switched. The problem is the old kernel as you guessed right. There is no way to use could not remove module resource temporarily unavailable the "option" driver in your version; so the "usbserial" driver has to could not remove module device or resource busy be used. This is not (yet) automated in usb_modeswitch. But I might add it in the future. Do
Rmmod Device Or Resource Busy
a "modprobe -v usbserial vendor=0x12d1 product=140c" and see if you get ttyUSB ports. Top boran Posted: Thu Sep 09, 2010 5:11 pm Posts: 6Joined: Thu Sep 09, 2010 4:26 pm
Rmmod Error Module Is Built In
I see. But no, doesn't work that way either. modprobe -vvv usbserial vendor=0x12d1 product=140c ls -al /dev/ttyU* ls: cannot access /dev/ttyU*: No such file or directory I also tried removing modules first, just in case: rmmod usb-storage rmmod usb-serial lsusb Bus 001 Device 006: ID 12d1:140c Huawei Technologies Co., Ltd. modprobe usbserial vendor=0x12d1 product=0x140c Top Josh Posted: Thu Sep 09, rmmod error module is in use 2010 5:17 pm Site AdminPosts: 5860Joined: Sat Nov 03, 2007 12:30 am O.K., please turn on logging as indicated on the doc page, paragraph "Troubleshooting". Also, post what "dmesg" says after trying to load "usbserial" (the last 30 lines or so).

However, the newest rmmod return code devices may not be currently included in the driver.This guide consists of example USB device installation instructions using either driver load time parameters or modification of the device driver to natively support the device. There are http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?p=3307 often subtle differences in Linux distributions. Any distribution specific conflicts should be resolved by consulting the distribution's documentation. Option 1: Serial USB Installation Instructions (No Recompile Necessary) Notes: Commands preceded by '$' can be issued by user-level privileges.Commands preceded by '#' require root-level privileges.This method will ONLY work with single and dual port devices. Any device with more than two ports requires a driver modification and recompile (see Option 2 below). http://www.sealevel.com/support/article/AA-00524/0/How-to-configure-USB-serial-adapters-in-Linux.html 1) Plug in the Sealevel USB device(s). 2) Open a terminal window and attain root privileges. This varies by distribution, but the most common method is to use the su command as demonstrated below. $ su -Password:# 3) Ensure that the device has been detected by the USB subsystem. This can be accomplished by using the lsusb command as demonstrated below. The -s 0c52 parameter returns only information about Sealevel devices attached to the system's USB subsystem. For this example, we will attach the device driver to the e402 Sealevel hardware, which is the USB to RS-485 bridge used in Sealevel SeaI/O U-series data acquisition modules. # lsusb -s 0c52Bus 002 Device 011: ID 0c52:e402 Sealevel Systems, Inc.Bus 002 Device 010: ID 0c52:2101 Sealevel Systems, Inc. 4) The kernel driver module for all FTDI based USB serial devices is sometimes configured for automatic load at boot time. Depending on distribution, it may be necessary to unload the driver if it is already loaded. This can be achieved by issuing the following command. This command can be issued without detriment when the driver is not loaded. # modprobe -r ftdi_sio 5) The FTDI serial USB driver in Linux contains many product IDs for Sealevel devices.

There's a kernel module normally loaded first, and daemon establishing netlink socket with the module. The issue here is that after killing the daemon, I'm no longer able to unload the module from the memory: % rmmod _module.ko % rmmod: _module.ko: Resource temporarily unavailable Analysis has shown that error (return value is -11, i.e. EAGAIN?) is returned by try_stop_module() invoked in syscall delete_module() definition in kernel/module.c. Function try_stop_module() is in use in turn calls stop_machine() and this is where I've stuck, as I'm not sure what's exactly happening there. I think the root cause is somewhere in the daemon that opens connections to the module and obviously something else and doesn't correctly close/clean-up on exit (apparently some references/locks are not released?) Does anybody have any idea what else to look at and probe? linux linux-kernel kernel-module share|improve this question edited Dec 13 '12 at 10:53 ymn 1,68311230 asked Dec 12 '12 at 19:33 Mark 1,04231533 Just a stupid idea ... rmmod -f ... forcing the unload? –ernestopheles Dec 12 '12 at 20:39 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote First of all you should be a superuser to do this. Also you can use rmmod -f but this option can be extremely dangerous: it has no effect unless CONFIG_MODULE_FORCE_UNLOAD was set when the kernel was compiled. With this option, you can remove modules which are being used, or which are not designed to be removed, or have been marked as unsafe. Also read man rmmod. share|improve this answer answered Dec 13 '12 at 10:51 ymn 1,68311230 thanks for comments. I'm aware of 'forced' mode, however on my platform busybox's rmmod isn't compiled with this option, and my aim is to figure out what descriptors

When I run the "modprobe option" command, I get an error message saying "FATAL: Module option not found.".Can you please let me know how to enable this module?Thanks, Harun Logged Christian Jann Newbie Posts: 24 Karma: +3/-0 Re: How to enable option module « Reply #1 on: December 22, 2012, 02:00:20 PM » Hi,If you want to be able to load kernel modules you need a kernel with "loadable module support", it is likely that you are using a kernel where this was not enabled. So you have to rebuild your kernel with "loadable module support":Code: [Select]Loadable module support --->
[*] Enable loadable module support
[*] Module unloading
[ ] Module versioning support (EXPERIMENTAL)
[*] Automatic kernel module loading
I've tested it on my laptop:Code: [Select][chris@thinkpad ~]$ sudo modprobe option
[chris@thinkpad ~]$ lsmod |grep option
option 34230 0
usb_wwan 19189 1 option
[chris@thinkpad ~]$ locate option.ko
/usr/lib/modules/3.6.10-2.fc17.x86_64/kernel/drivers/usb/serial/option.ko
/usr/lib/modules/3.6.8-2.fc17.x86_64/kernel/drivers/usb/serial/option.ko
/usr/lib/modules/3.6.9-2.fc17.x86_64/kernel/drivers/usb/serial/option.ko
You probably also need to enable:Code: [Select]Device Drivers --->
[*] USB support --->
<*> USB Modem (CDC ACM) support
<*> USB Serial Converter support --->
[*] USB Generic Serial Driver
<*> USB driver for GSM and CDMA modems
[*] Network device support --->
<*> PPP (point-to-point protocol) support
<*> PPP support for async serial ports
What do you want to do, maybe there is another way to achieve this, where do you have read that you should run "modprobe option".I think it is the better to rebuild the kernel with the needed modules built-in and not as a module e.g. you select [ * ] instead of [M] when configuring your kernel. « Last Edit: December 22, 2012, 02:23:19 PM by chris-j » Logged Harun Newbie Posts: 3 Karma: +0/-0 Re: How to enable option module « Reply #2 on: January 05, 2013, 11:05:11 AM » Hi,I work on connecting my Olinuxino-Maxi to internet using a 3G dongle but it is a Huawei HiLink modem, it acts as an ethernet interface, not usb.
