OK this is somewhat of a stupid question as I'm already having a hard time writing it down.

I am currently writing a software that directly controls a USB device. OK to give you something to flame me - i am doing it in VB6 (Doh). Yeah we can spend like 3 hours discussing how noob that is, but if possible lets still get to my question as it is somewhat generic.

I have sniffed the device (Its a disco light kinda keyboard, you can program the lights) and so i know to initialize the device the program sends an AOB to the device. Lets say it sends "02 02 12 0A 00 00 80 02". The real array is a bit longer, but whatever.

My idea was to hardcode these AOBs in my app, but i already fail at assigning these.

For a string its easy, i would do it like "dim myString as String" and then "myString = "lolthis is the string"

For an array of bytes i am having many problems. The main problems is obviously my head as i dont think or dream in bytes... XD

I tried it like

"Dim myBytes() as Byte"
"myBytes = "02 02 12 0A 00 00 80 02"

Obviously this aint work. I am always having a hard time with arrays. I know it is probably working when i do it like

"myBytes(0) = 2"
"myBytes(1) = 2"
"myBytes(2) = 12"
"myBytes(3) = 0A"

Well at least close to that. But it gives me an error for 0A and it would make me crazy to write a line of code for every damn single byte.

I am aware i could use like

Dim myarray() As Byte
myarray = StrConv(mystring, vbFromUniCode)

to convert a string to an array of bytes. But the problem is i have no string, the bytes send are not readable in most cases, its just glibberish, nothing i could save to a text file.

I hope someone understands my problem. After we solved it i am willing to play victim for all VB6 hater flamewars. Actually i would also accept solutions in .net or similar, but no assembler, cobol or random crap please.

The second solution helped me a lot, thanks!!!

Gaaah, i spent about 2 hours just to realize the module by Intel i use is bugged terribly, it doesnt read out the device name properly. Damn you Intel!!! Razz

lol@me noob fixing Intels bugs... XD

Wah, i approach slowly. First time i ever made an app to communicate with a USB device. I really hope i get this done as the original Software for my Luxeed Keyboard totally stinks! It was programmed by ppl even dumber then me or terribly lazy i think because it totally lacks features.

Thanks, i totally love it. But the software STINKS! You cant even make your own animations although it is technically no problem. Its fucking 3rd world software, damn. As much as i like korean software (<3 maple) this is total BS.

However, i am having problems with my write function. I wanna write some bytes to the keyboard and always fail.

dunno if this helps you

Well i always get back 0 and nothing is sent to the device. I know for sure as i am sniffing with Advanced USB port monitor. My OpenDevice works, i can see the packages in the monitor. However, the WriteUSBDevice always fails with 0 and i have not been able to find the reason yet. It simply doesnt send anything, absolutely nothing in the monitor.

check this link out, see if anyone had an answer

the guy is writing a driver for some controllers he bought to make a Quiz game.

However, he seems to have the same problem as u

Yeah the post looks promising, but i still don't get how he solved the problem. I tried the read function he posted and then i get "could not write input report".

I'm too tired for today, i will spent more time with it tomorrow. Thanks for the help so far.
