Any USB piece of equipment I plug into my laptop, takes an age to be recognised... As soon as I plug it in, I get the familiar ding-donk noise, but its almost a min before I can use it. The XP laptop however, assigns a drive letter, and I can access it within seconds.
I have done some reading up on this, but no-one seems to have a hard solution. I downloaded a patch ages ago, that was meant to cure an issue with an early M$ update for Win 7 and USB. The laptop runs Win7 Home premium 64bit, and is an HP G61-410SA. Other than this, it runs absolutely fine, with no other issues at all. I can live with it, but wondered if this was a general Win7 issue, or just something specific to the laptop. I updated the chipset drivers last night, from HP, still the same....

However it may be worth checking the bios settings
Mine have the following and it might be worth checking if the last one is active
USB Controller
USB 2.0 Controller
USB Keyboard support
USB Mouse support
Legacy USB storage detect

Equally I have no idea whether it will have any effect as it is only supposed to support it during boot to recognise USB drives

Its not that its not recognising the USB device, it does this almost immediately. its the time it takes to let you access the data on the drive.
File transfers once operational, seem quick enough, but not sure what transfer speeds are deems OK for a USB2 pen drive..

The only other reason I can think of is that your antivirus software scans the USB drive for malware before allowing any access to it.

At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

I have an HP dv6 laptop running Win 7Home Premium 68 bit. There is no oddidity in connecting to printers, external HDs etc., but i have a Garmin 2440 which needs its maps to be updated. The Sat Nav runs perfectly plugged into one of the USB outlets but Win 7 does not "see" it. I have downloaded all the bits from Garmin including a Garmin USB driver as well as the map update, all to no avail. No amount of fiddling seems to solve the problem and Garmin only offers vague ideas s to what could be wrong. Any clues out there?
An associated problem that I have is with my old Dell OptiFlex G110 running XP Pro 32 bit. It sees my Astra 1220U OK but when I try to use the scanner with its original software, it all opens up fine except that I get an error message saying "cannot find the scanner"! The set-up used to work perfectly with my even older Win98SE (now defunct). Is there any way that the addressing of the route to the USB can be adjusted? My Canon scanner of the same vintage works fine.

AIUI Windows "remembers" a list of the appropriate driver set for any USB device EVER plugged in. When a USB device is plugged in Windows searches the list for the appropriate drivers ( If it doesn't find them it goes through the add device routine). If you get a problem in the list - a bad driver or a bad file reference or simple corruption it can really make a mess of the ability to attach USB devices. In the worst case the list search fails and the USB device is never recognised.
Windows will not let you uninstall a USB device unless it is attached, but USBDeview will. If its just one device that has a problem try uninstalling the drivers for the problem device. If its just one hub or port deinstall those. If its all USB devices it suggests that the list structure or something in the list may be a problem, and you might need to try getting rid of devices that you attached long ago and no longer use. In the limit delete them all, reboot and let windows add them back as you use them again.
Its a slow and painful process to diagnose the problem, but those two bits of freeware can help.
