USB Bluetooth Dongles not working on USB 2.0 Hubs
Last modified: 2015-01-04 17:13:39 EST
Description of problem:
i donÂ´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 ÂµPD720113
Version-Release number of selected component (if applicable):
I have this problem with Suse Linux 9.2, Fedora Core 3 and Mandrake
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"
Bluetooth not working on USB2.0 Hubs.
Bluetooth working correctly on USB1.1 Hubs or without any USB-Hub
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
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 donÂ´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 havenÂ´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.
The upstream usb developers have their own mailing list at
email@example.com Sending a description of your problem
there will likely get a response from someone who knows whats wrong, or has clues
for further investigation.
