Hi: I have one device called "entropy key" http://www.entropykey.co.uk/ 9: USB 00.0: 10200 Modem [Created at usb.122] Unique ID: hhw5.xbUS5LcXf33 Parent ID: FZIx.RTX9xWW_uz4 SysFS ID: /devices/pci0000:00/0000:00:1d.2/usb8/8-1/8-1:1.0 SysFS BusID: 8-1:1.0 Hardware Class: modem Model: "Simtec Electronics Entropy Key" Hotplug: USB Vendor: usb 0x20df "Simtec Electronics" Device: usb 0x0001 "Entropy Key" Revision: "2.00" Serial ID: "M/9uBjBLNzE3QSFD" Driver: "cdc_acm" Driver Modules: "cdc_acm" Device File: /dev/ttyACM0 Device Files: /dev/ttyACM0, /dev/serial/by-id/usb-Simtec_Electronics_Entropy_Key_M_9uBjBLNzE3QSFD-if00, /dev/serial/by-path/pci-0000:00:1d.2-usb-0:1:1.0 Speed: 12 Mbps Module Alias: "usb:v20DFp0001d0200dc02dsc00dp00ic02isc02ip01" Driver Info #0: Driver Status: cdc_acm is active Driver Activation Cmd: "modprobe cdc_acm" Config Status: cfg=no, avail=yes, need=no, active=unknown Attached to: #18 (Hub) which works just fine most of the time, except that it has never-ever recovered after suspend/resume, the only way to make it "live again" is plug/unplug the device after resume, or with an pm script #!/bin/bash . /usr/lib/pm-utils/functions case "$1" in hibernate|suspend) stopservice ekeyd modunload cdc-acm ;; thaw|resume) modreload cdc-acm restartservice ekeyd ;; *) ;; esac exit 0 and well, that's really *really* ugly. Looking at the USB quirks list, looks like this device needs USB_QUIRK_RESET_RESUME, I am not a kernel developer so Im not sure about if this is correct. will be cool if someone can add the quirk if it is the correct one or point me to the right approach. ;) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
