I am having trouble getting the code correct to read the USB.  I have connection but not sure of the correct way to code to get the BulkRead() to read the data from the port and put into a string.

Can anyone help me with this???????

const int VENDOR_ID = 4505;

const int PRODUCT_ID = 25703;

Device device;

Anyone??  I am still in desperate need of help!!  I just need to know how to write up the code to do the reading and get the data from the device into a string.

I ran the TestLibUsb.exe to get the device info. and here is what it has:

Hi! I have a similar problem, but you haven't used correctly the function BulkRead.

This function doesn't return a value but take in input two parameters:

int endpoint, byte[] msg

msg is an array defined before where the byte read from the endpoint was put.

but how endpoint do I use???

Something can response this question? There was another methodto use before the bulkread? For example, what does SendControlMessage do?

Thanks.
