(including pointers) Yup. No wait, it's actually 2 different messages repeating, here's both of them repeating: drivers/usb/host/uhci-hcd.c: uhci_result_common() failed with status 440000 [dec132a0] link (1ec13152) element (1ec00090) 0: [dec00090] link (00000001) e0 SPD IOC Stalled CRC/Timeo Length=7ff MaxLen=1f DT0 EndPt=2 Dev=3, PID=69(IN) (buf=1f9c8ec0) hub 2-0:0: port 2, status 100, change 3, 12 Mb/s drivers/usb/host/uhci-hcd.c: uhci_result_common() failed with status 440000 [dec13270] link (1ec13152) element (1ec00090) 0: [dec00090] link (00000001) e0 SPD IOC Stalled CRC/Timeo Length=7ff MaxLen=1f DT1 EndPt=2 Dev=3, PID=69(IN) (buf=1f9c8ec0) drivers/usb/host/uhci-hcd.c: uhci_result_common() failed with status 440000 [dec132a0] link (1ec13152) element (1ec00060) 0: [dec00060] link (00000001) e0 SPD IOC Stalled CRC/Timeo Length=7ff MaxLen=1f DT0 EndPt=2 Dev=3, PID=69(IN) (buf=1f9c8ec0) drivers/usb/host/uhci-hcd.c: uhci_result_common() failed with status 440000 [dec13270] link (1ec13152) element (1ec00060) 0: [dec00060] link (00000001) e0 SPD IOC Stalled CRC/Timeo Length=7ff MaxLen=1f DT1 EndPt=2 Dev=3, PID=69(IN) (buf=1f9c8ec0) Then in the middle of these, I see this one which is different: drivers/usb/host/uhci-hcd.c: uhci_result_control() failed with status 440000 [dec132a0] link (1ec131e2) element (1ec00090) 0: [dec00090] link (1ec000c0) e0 Stalled CRC/Timeo Length=7 MaxLen=7 DT0 EndPt=0 Dev=3, PID=2d(SETUP) (buf=1ecf59c4) 1: [dec000c0] link (1ec000f0) e3 SPD Active Length=0 MaxLen=1 DT1 EndPt=0 Dev=3, PID=69(IN) (buf=1eb9f2bc) 2: [dec000f0] link (00000001) e3 IOC Active Length=0 MaxLen=7ff DT1 EndPt=0 Dev=3, PID=e1(OUT) (buf=00000000) > > Any ideas of how to fix this, or even what is causing this continuous > > message (I can see it happening once, but not more than once.)

I don't think this is a new thing, I think I've seen this in the past, but haven't really tested removing devices a bunch on this machine before (it's a USB 2.0 controller with a UHCI controller for the "slow" part.) > I'll take a look at the code.
