Trying to get my IOGear GBU421 to work on F14

socialdeviat · #1 14th March 2011, 06:46 AM

I am a complete nubile to Linux in general, just about 2 weeks of fun so far. I've basically replaced my windows installation, and I am not looking back. I have a IOGear GBU421 USB Bluetooth Adapter and I can't seem to get it to be recognized in Fedora 14. Any help? Thanks

I have the GBU221 usb device and plug it in to my F14 computer and a Bluetooth icon appears on the panel.
You can open a terminal and enter "lsusb" and your device should be listed there if it is recognised. Then under
System>Preferences>Bluetooth you can view preferences or from the Bluetooth panel icon.

That is what I keep hearing, but when I do, nothing happens at all. Perhaps my adapter is just bunked. I'll have to try it on another pc, and see if I get the same result.

When you insert the IOGear into the usb port do you see the btusb module is loaded?

Check in a terminal:

Quote:

lsmod | grep btusb

the btusb module handles general usb bluetooth support
(try running "modinfo btusb" in the terminal and you'll see its module statement)

Also make sure Linux is at least seeing it at all, if you plug in a usb device in general you should see a message show in the Kernel message buffer:

Code:

dmesg

Since those entries are time sorted it would be right at the bottom

Code:

lsusb -v

will show the verbose 'list usb' of all the usb devices plugged in, your device should be one of them.

the point is to see if the device is completely not seen or if it's seen (dmesg shows it) but the module isn't loaded for bluetooth.
In the latter case you can load the module and continue from there:

Quote:

modprobe btusb

When i insert the module, nothing happens. At all... whatsoever. Many say I am supposed to get the icon in the panelbar, but I don't even get anything if I go to system>preferences>bluetooth... says no adapters are present

But is the btusb module loaded? You should see something like this.

Quote:

lsmod | grep btu

btusb 15514 3
bluetooth 89276 7 btusb

If not, then try loading it manually:

Code:

su -c 'modprobe btusb'

(loading btusb will pull in bluetooth automatically)

Heres what I got for both of those, where do I go from here?

Post the output of
lsusb -v
as you were repeatedly told.

Assuming its that one, since everything else clearly states keyboard or usb hub, what does that mean? (pardon me for not being completely fluent in navigating the shell there Stevea) Still learning

You might also want to check if Bluetooth Manager is enabled in the "Startup Applications" list.
Go to System>Preferences>Startup Applications and see if the BT Mngr. is enabled if not place
a check there and restart computer and see if BT icon appears when the BT device is plugged in.

socialdeviat · #11 16th March 2011, 12:11 AM

Yes BT Manager was already selected.

ryptyde · #12 16th March 2011, 01:39 AM

Try checking your device by opening a terminal and entering

Code:

hciconfig

and then as root (su) enter

Code:

hciconfig hci0 reset

and see if that gets it to
show a BT icon. You may have to restart the computer. I got some of this info by googleing
and also by reading the man page for hciconfig. You can read the man page from the terminal
by entering

Code:

man hciconfig

thanks, i'll post what i find

---------- Post added at 05:59 PM ---------- Previous post was at 05:49 PM ----------

Code:

[Deviat@deviatedit ~]$ hciconfig iscan
Can't get device info: No such device

Code:

[Deviat@deviatedit ~]$ hciconfig
[Deviat@deviatedit ~]$

Code:

[root@deviatedit Deviat]# hciconfig hci0 reset
Can't get device info: No such device

not showing me anything at all. Tried every command which made sense to try in the manual too...

ryptyde · #14 16th March 2011, 02:22 AM

I'm at a loss as what to try next. There is the possibility that the Broadcom chipset
is just not supported in Linux at this time. Even though someone else's device with
the same model number works the chipset could be different. I have found that out
trying to get Belkin wireless usb dongles working, chipset matters. If you can return
that device and check if there is a revision number on the box or package it came in
and try one with an earlier or later number. Pain in the rear I know but sometimes you
have to put a little extra effort.

EDIT: one more place to check System>Services>bluetooth and see if is enabled and running.
