Summary0005259: jvHidDeviceController HID devices don't work in delphi 2010
DescriptionThe jvHidDeviceController component (in jvHidController.pas) doesn't work in delphi 2010. If you compile and run the standard examples that come with the component in the examples directory such as: BasicDemo and SimpleHIDWrite that work perfectly in delphi 7; they raise an exception when running.
Additional InformationI think it has something to do with incompatibility with the Unicode strings of Delphi 2010
TagsNo tags attached.

No such problem in D2009, so this is not a Unicode related issue.
Please try again using the latest SVN version, this might already be fixed

The exception problem turned out to be from a multi-touch screen input device attached to a USB port once disconnected; the exception dissapeared.

The exception problem turned out to be from a multitouch screen; so when I disconnected the multitouch screen's usb cable; the exception dissapeared.

But there is a difference in the received data between delphi 7 and Delphi 2010.
I connected a Griffin PowerMate Knob and checked the data received in the SimpleHIDWrite example compiled first in Delphi7 and then Delphi2010; as you can see from the two screenshots I have attached; the data is not interpreted correctly.
