*Not sure if this is the appropriate forum if not could i be directed to the\nright one although i feel this is pretty close if not the right one*\n\nProblem:\n\nI have noticed before and was curious and & thought this would be the happy\nplace to find the answer and is related to microsft windows Vista. Im having\na few troubles with my PC, sometimes won't go out of sleep mode and\ndissconnecting USB devices randomly when entering sleep mode and it could\ndissconnect the soundcard (usually does) and the mousse still works, or the\nmousse won't work either after entering sleep mode. None of this should be\nhappeneing as USB devices should'nt be dissconnecting in sleep mode, and i\nhave checked out all options in "power options" and everything is set\ncorrectly so there is no reason that USB devices should be randommly\ndissconnecting. Anyway heh. I have been onto the toshiba forums and have\ndownloaded the BIOS and display drivers from toshiba as some said may help.\n\nAll this had me thinking and i thought because there is so many problems\nrandomly happening and there are a few areas in which iam unsure of, i\nthought i would ask about one of them to whoever may wan't to help me to\nclear atleast some of this mess out of my head and give me a bit better\npicture of whats going on with my PC.\n\nHeh, Ok, Question: This has bewildered me for ages, a while now, and wan't\nto clear some of the confusion out so here we go. There is a list of USB host\ncontrollers & USB Hubs corresponding to these Host controllers. What are they\nfor. It seems that when ever i have a USB device plugged in it shows up as a\nseperate device (whatver) in device manager so i was wondering what the other\ncontroller and hubs were for? Hope someone can help. Also to add to the\nquestion, going back to what i said previously at the start of this message,\nthe randomly dissconnects devices when entering sleep mode, by randommly i\nmean sometimes when the PC enters sleep mode sometimjes devices dissconnect\nsometimes they don't(soundcard dissconnects most times if not all the time,\nhave not kept tabs, have to check..). When i enter windows again replug the\nmousse in most times it will recognise but the soundcard will show in device\nmanager but not in "soun options" and will say this device is working\nproperly in device manager when obviously i can't use it. It sucks. Is there\nany pattern forming here or is it time to send the Lappy in for a check up.\nIt was sent in once before to get the HD replaced because of bad sectors and\nwas dropped and damage was done to the left side of the alptop where the 2\nleft USB ports are situated, but on the side i connect my mopuse and\nsoundcard to there was no damaged atleast on the outside and don't think it\nlanded/damaged on that side.\n\nIf you need information on my Laptop it is a\nToshiba Satelite A300 PSAGCA (08W model i think), pm45 chipset, T9400\nprocessor.\n\nIf you need more info let me know.\n\nThat is it...\n\nHope someone can help solve my problem, or help.\n\nCheers Thankyou,\n\nLee.
