Hi all, Sorry to spam you guys. I recently encountered a issue that I can't figure out how to fix it, so I write to you and hope some of you can give me hints. The issue is ath3k easily fails to load its firmware when the USB port is switchable(EHCI -> XHCI). ath3k: probe of 2-7:1.0 failed with error -110 Sometimes it fails to load the firmware when boot up, sometimes it fails when resume from S3. I try to set the D0 register to 0 to force it use EHCI, then it works well. Disable the USB 3.0 function from BIOS, it also works well. And another workaround is to delay loading the ath3k module around 30 seconds, it can load the firmware without problems. It's not only happened on a certain Atheros chip, we've encountered this issue on many Atheros chips. To get rid of this issue, please give me some hints, I can help to verify your ideas. Best regards, AceLan Kao. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
