Hello Programmers, At many new USB Devices (in my case a PDU - Power Device Unit) they are using more in more "usbhid". Now I want to setup some of my devices with Microcontrollers and USB device controllers, which I want to use over "usbhid". Does anyone know, where I can get Specifications (anything about it and not only PDU/UPS) or can tell me how I can code it? (I can not imagine that it is only text/plain over USB. It seems the protocol is more complex) Also my DS8xCxxx (using "sdcc") and LH4A4xx (ARM922T) are forking nicely and I have all Data available but I do not know, how I should send the Data on request by the Host, e.g. from NUT (Network UPS Tool) over the USB... Also I should say, that I can flash the DS80C411 perfectly over USB from my ThinkPad 570 running Sarge/Etch. And even uploading/flashing a whole Debian-ARM system of up to 8 MByte into the NV SRAM to my LH7A411 is now working... Oh, I had to code my own bootloader which was more simple as I was thinking a I have encountered that I have two memorys where the first internal one was started and look for a flag and if the flag was set, e.g. from an external switch, the controler start the flash routie and try to suck an image over USB or any other serial ports... If the flag was not set it depends since it can run a program from the internal 64kByte EEPROM or switch the memory to the extenal one and execute its content... Hell reading the specs from NXP where I have found some lines of a basic bootloader... those 10 lines of ASM are mutatet to over 4kByte... :-) Thanks, Greetings and nice Day Michelle Konzack Systemadministrator 24V Electronic Engineer Tamay Dogan Network Debian GNU/Linux Consultant -- Linux-User #280138 with the Linux Counter, http://counter.li.org/ ##################### Debian GNU/Linux Consultant ##################### Michelle Konzack Apt. 917 ICQ #328449886 +49/177/9351947 50, rue de Soultz MSN LinuxMichi +33/6/61925193 67100 Strasbourg/France IRC #Debian (irc.icq.com)
