Hi,

I am trying to connect o an Abbott Freestyle Freedom Lite blood glucose
meter on Win 7 64 bit and get the following exception:

Exception in thread "main" javax.usb.UsbPlatformException: USB error 12:
Can't open device Bus 001 Device 002: ID 1a61:3410: Operation not supported
or unimplemented on this platform

Is there a known work around or another way of connecting to a device?

Endpoint descriptors are as follows:

Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x01 EP 1 OUT
bmAttributes 2
Transfer Type Bulk
Synch Type None
Usage Type Data
wMaxPacketSize 64
bInterval 0

Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x83 EP 3 IN
bmAttributes 3
Transfer Type Interrupt
Synch Type None
Usage Type Data
wMaxPacketSize 2
bInterval 1

Full stack trace:

Exception in thread "main" javax.usb.UsbPlatformException: USB error 12:

or unimplemented on this platform

Any help would be appreciated,
