Description Daniel 2004-12-07 14:46:33 UTC
Description of problem:
i don´t know if i am right here, but i found a problem:
I have always the same bug, or i am to stupid:
If i connect a USB Bluetooth Dongle with CSR chip to the USB Port it 
works correctly. If i connect an USB 1.1 Hub and connect the 
Bluetooth Dongle there, it is also ok. 
But if i connect it to a USB 2.0 Hub, it is not detected correctly. 
The Hub is working, but the dongle not. 
I tested with this USB2.0 Hubs:
- Cypress 4-port CY7C65100
- NEC 7-port µPD720113

Version-Release number of selected component (if applicable):
I have this problem with Suse Linux 9.2, Fedora Core 3 and Mandrake 

How reproducible:
Connect USB Bluetooth Dongle with CSR Chip to an USB2.0 Hub. 

Steps to Reproduce:
1. Connect CSR Bluetooth Dongle
2. Open Console
3. type "dmesg"
Actual results:
Bluetooth not working on USB2.0 Hubs. 
Bluetooth working correctly on USB1.1 Hubs or without any USB-Hub

Expected results:
Bluetooth should work, like connected without USB Hub

Here are some hardware details:
Mainboard: Asus P4P800S or Asus P4C800 Deluxe

Here is the output from dmesg, when the Dongle is connected to a 
USB2.0 Hub:
usb 5-2.4: new full speed USB device using address 15
ehci_hcd 0000:00:1d.7: qh cd305600 (#0) state 1
hci_usb_intr_rx_submit: hci0 intr rx submit failed urb c203db14 err â

This is no problem with cables or defective Dongle, replaced all 
parts. Seems to be a general problem.

this is probably best brought up with the upstream usb developers.

> this is probably best brought up with the upstream usb developers.


I have used Linux for 2 weeks now, so i simply don´t know where to ask. 
I reported the problem in 5 newsgroups before.
Each newsgroup is telling me something different. 

I have not developed the linux core, i only know there is a bug inside.
I am very interested in a bug-fix, but i haven´t the time to find 1 out of 
10000 developers who want to fix it.
It seems like no one cares about this bug, it seems like no one is responsible.

Comment 5 Dave Jones 2004-12-08 16:58:20 UTC
The upstream usb developers have their own mailing list at 
linux-usb-users@lists.sourceforge.net   Sending a description of your problem
there will likely get a response from someone who knows whats wrong, or has clues
for further investigation.


Comment 6 Dave Jones 2005-07-15 20:04:37 UTC
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

Comment 7 Dave Jones 2005-09-30 06:40:14 UTC
Mass update to all FC4 bugs:

An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel ( As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.

Please retest with this update, and update this bug if necessary.


Comment 8 Dave Jones 2005-11-10 19:43:19 UTC
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.

Thank you.
