I have a Viper Emedded Linux Developer Kit Pre-Build Kernel 2.4.21 My Problem is that USB somehow crashes my Device. (USB Bluetooth Dongle) It occurs on higher USB traffic (for example) or doing the following:
[EMAIL PROTECTED] root# hciconfig hci0 -a hci0: Type: USB BD Address: 00:04:61:81:11:3C ACL MTU: 192:8 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:107 acl:0 sco:0 events:14 errors:0 TX bytes:299 acl:0 sco:0 commands:13 errors:0 Features: 0xff 0xff 0x0f 0x00 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: HOLD SNIFF PARK Link mode: SLAVE ACCEPT Name: 'BlueZ (0) on viper' Class: 0x000100 Service Classes: Unspecified Device Class: Computer, Uncategorized HCI Ver: 1.1 (0x1) HCI Rev: 0x20d LMP Ver: 1.1 (0x1) LMP Subver: 0x20d Manufacturer: Cambridge Silicon Radio (10)
[EMAIL PROTECTED] root# hciconfig hci0 reset Can't init device hci0. Connection timed out(110) [EMAIL PROTECTED] root#
I already started a discussion on the BlueZ Mailinglist with this and other sides of my Problems. The Developer Marcel Holtmann pointed me to the direction that the USB Host Controller might actually be the Problem, because the "reset" command is an USB command and has not much to do with Bluetooth.
The USB Host Adapter driver that Arcom uses is "hc_isp116x". I googled and found that its manufactured by Philips. But why is the USB Host Conroller named hc_isp116x? On a normal Linux PC a UHCI or OHCI driver is running. The Product sheet says the Chip is OHCI compatible. "Enhanced Original USB OHCI-compliant host with two downstream facing ports" Can I use the Linux OHCI driver? Or is this only a renaming of the OHCI driver? I don't understand why to use this special driver.
On my normal Linux PC everything works fine. No such Problems. Can you point me to what to do or what else could be the Problem? I really appreciate any help or comments.
