which kernel did you use? I've currently checked that on a SuSE10, kernel 2.6.13 and turned on CONFIG_USB_SUSPEND - no problems so far. I tried to put the LiDE20 into suspend - no problems. Next thing I need to check is my laptop, running a SuSE10.2 - kernel2.6.18 It's quite strange - from reviewing the code there's only one point which could cause the mentioned problems - but not on a Lide :( - Gerhard
