Hi everybody, if I suspend to disk I loose the USB hub. I also tried to unload the related modules before suspending: SUSPEND_MODULES="button uhci_hcd ehci_hcd usbhid usbcore" The messages (see below) report an error related to uhci_hcd and HCRESET, I googled the problem but I couldn't find a solution. Does anybody have experience with this? Many thanks, G Feb 13 18:12:45 cms09xl kernel: usb usb4: root hub lost power or was reset Feb 13 18:12:45 cms09xl kernel: ehci_hcd 0000:00:1d.7: debug port 1 IN USE Feb 13 18:12:45 cms09xl kernel: PCI: cache line size of 32 is not supported by device 0000:00:1d.7 Feb 13 18:12:45 cms09xl kernel: ehci_hcd 0000:00:1d.7: PCI post-resume error -19!
