So I decided to stop feeling around in the dark and just compiled your source directly into my test program.

I found that in the IowiFillInList function, your case statement is missing any reference to the IOWPV1 or 2.

Here's the original code:

switch (hidAttr.ProductID)
{
case IOWKIT2_PID ...

I must be misunderstanding the documentation. I just tried doing a write to interface 0 with function 0x20 then chased it with a read on interface 0 and that works as advertised. Here is the bit from the manual:

5.7.4 Power status functions
IOW24PV has a function to read back the power
mode it has ...

No, this can not be a electrical problem, the status should be returned in any case as long as the chip is basically working (which it does if it shows up on the USB).

Have you used "SimpleHIDwrite" to manually send the stuff and look at the results? You can find it in the SDK in Samples/General ...

but all the values for specialmode-sequences that start with $ are Hex-values.

Ya, I tried it as hex also, same problem. The write never returns.


So there could be 2 reasons why the write fails:
the software gets confused because of the invalid command for the chip
or
the chip itself gets on ...

The new software (beta) helped the basic access problem. I am now able to open a connection, retrieve version information, chip revision, serial number, etc.

But when I try writing to the chip it either fails writing zero bytes or hangs depending on which pipe I write to. For example, I am trying ...

When running the demo download it claims:

"No IO Warrior Attached” or something similar.

My program gives me a NULL return when I run IowKitOpenDevice().

GetLastError returns 0.

I am using the SDK from July 21st 2005 and IOW24PV-P V1.0.2.3R


Microsoft HID recognizes the device when ...

I am using 1.0.2.2

When attempting to recognize the USB device in Windows XP I receive the error message: This device cannot start. (Code 10). I have created a circuit using the schematic in the IOW24PV documentation.
