This falls into the aggravating and interesting, but not fatal category.
USB device: SanDisk "ImageMate 6 in 1" device that can hold up to 4 camera memory cards at one time
Computer A: Compaq running XP SP2
Computer B: HP running Vista Home Premium
Router: Linksys Wireless G Broadband Router
I have had the USB connected to Computer A for a couple of years with no issues. During that time, the USB appeared on Computer A as a USB device and the 4 slots appeared as 4 'Removable Disk' entries in the Explorer. I have had and still have a 512MB card in the first slot. The other slots are empty. The Router was connected to two machines at that time: both XP SP2.
Last year, I connected Computer B to the network and removed the older machine. A few months ago, the USB drives (the 4 slots) began appearing on Computer B's Explorer as 4 Removable Disks -- i.e. as if the USB device were plugged into Computer B. And, Computer A no longer shows the 4 Removable Disks -- i.e. as if the USB device were NOT plugged into Computer A. Also, exploring Network from Computer A shows the 4 drives on Computer B. Both computers agree that the Removable Disks are connected to Computer B -- but, neither computer can access the 512MB memory card.
I have repeatedly checked (in complete disbelief) the wire from the USB device to Computer A. It is definitely connected to Computer A.
Further, the 'Safely Remove Hardware' for Computer B shows a USB device connected. But, NO external USB devices are plugged into Comptuter B. And, Computer A, consistently, does not show the USB device connected at all.
Both computers have been re-booted multiple times. I have disconnected the USB and rebooted, reconnected and rebooted, etc.
I have Norton running on both machines. I have run anti-spyware also.
This is not a fatal problem for my network, so I have not pursued it aggressively. However, it is a 9.3 on my weird-s__-a-meter. Before I start looking at it again, thought I would run this by the experts.
Any thoughts on what could be causing this behavior?
