(The latter with the "gavin-usb-controller-patch" however worked very well on this system!) Unfortunately, 8.2-STABLE didn't improve. On the contrary, no usb devices at all work after resume, so this is kind of a regression. I tested with a couple of different versions of the usb system and concluded that it is commit r229370 that makes the difference. After resume, the console says: uhub1: at usbus1, port 1, addr 1 (disconnected) uhub2: at usbus2, port 1, addr 1 (disconnected) uhub3: at usbus3, port 1, addr 1 (disconnected) uhub0: at usbus0, port 1, addr 1 (disconnected) What can I do to debug this further? It would be great to be able to sort this for 8.3. The laptop (Pentium-M CPU) has these usb controllers: uhci0@pci0:0:29:0: class=0x0c0300 card=0x052d1014 chip=0x24c28086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller *1' class = serial bus subclass = USB bar [20] = type I/O Port, range 32, base 0x1820, size 32, enabled uhci1@pci0:0:29:1: class=0x0c0300 card=0x052d1014 chip=0x24c48086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller *2' class = serial bus subclass = USB bar [20] = type I/O Port, range 32, base 0x1840, size 32, enabled uhci2@pci0:0:29:2: class=0x0c0300 card=0x052d1014 chip=0x24c78086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller *3' class = serial bus subclass = USB bar [20] = type I/O Port, range 32, base 0x1860, size 32, enabled ehci0@pci0:0:29:7: class=0x0c0320 card=0x052e1014 chip=0x24cd8086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB 2.0 EHCI Controller' class = serial bus subclass = USB bar [10] = type Memory, range 32, base 0xd0100000, size 1024, enabled cap 01[50] = powerspec 2 supports D0 D3 current D0 cap 0a[58] = EHCI Debug Port at offset 0x80 in map 0x14 Bengt
