this one has a different output, although I don't understand if it's working properly since there are still some fatal errors... there isn't a fatal error but a BOGUS error, as introduced by the patch.
http://arrakis.dhis.org/linux/laptop/dmesg-usbdebug-ehcipatch-2.gz
/sys/class/usb_host/usb4/registers contains:
bus pci, device 0000:00:1d.7 (driver 26 Oct 2004) EHCI 1.00, hcd state 1 structural params 0x00103206 capability params 0x00006871 status 0008 FLR command 010001 (park)=0 ithresh=1 period=1024 RUN intrenable 37 IAA FATAL PCD ERR INT uframe 3513 port 1 status 001010 POWER sig=se0 OC port 2 status 001010 POWER sig=se0 OC port 3 status 003002 POWER OWNER sig=se0 CSC port 4 status 001000 POWER sig=se0 port 5 status 001000 POWER sig=se0 port 6 status 001000 POWER sig=se0 irq normal 0 err 0 reclaim 0 (lost 0) complete 0 unlink 0
EHCI 1.00, hcd state 1 instead of the old value 0 means that the driver's working now?
care to comment? is this a good enough patch for the whole "usb community" or does it simply cover this isolated bogus error and by itself is unsafe for other environments?
