Driver and configuration utility; The MCP2200 appears as a USB CDC (virtual serial port) device. Windows already has a driver, but you need to assign it with an.inf file. The first time you plug-in adapter Windows will prompt for driver. Point windows to the.inf file supplied in the Microchip download.

MCP2200 Driver Installation Hi, I am trying to do a software-first installation of the mcp2200 driver using the Windows Driver Kit program DPInst. I place dpinst.exe in the same folder as MCP2200.inf (downloaded from under MCP2200 Drivers & Utilities).

On my windows XP x32 SP3 machine I get an install failed status, whereas it works fine on my win7 x64 machine. Now usually the.sys file is supposed to be in the same folder as dpinst as well as the.inf file, does anyone know how to obtain the MCP2200.sys file? I've read that it's name is usbser.sys. Is this a driver that comes preinstalled with windows? Is there another way of doing a software-first driver installation besides the use of DPInst? Edit: I checked the log of dpinst and it says it can't find the catlog file MCP2200.cat, the x64 machine says it already has the driver pre-installed so it may not be a 32/64 bit problem.

Is the cat file supposed to be supplied with the inf file, because it is not included. Pacer I assume you are aware that there are two versions of dpinst.exe? One for 32-bit and a different one for 64-bit. Your assumption is correct, I am running the correct version of dpinst.

I had a look at some of its configuration flags and it requires the legacy mode flag to install unsigned drivers. Legacy mode also installs drivers with missing files (in this case the.cat file). I have a feeling that signed drivers require a catalog file and maybe microchip doesn't want to release an unsigned driver to the public. Fire sprinkler calculation software free download.

Anyway, the legacy mode flag (/lm on cmd line) makes the install work.

Jump to:, Project Summary Name: MCP2200 breakout board Buy it: Price: $15 Status: Manufacturing: Forum:. The is a new USB to serial converter chip from Microchip. This breakout board brings all the pins to bread-board friendly headers. • USB CDC virtual serial port interface • Secondary HID configuration interface • Up to 8 additional IO • 256bytes user EEPROM • TX/RX indicator LEDs • All pins to bread-board friendly header The MCP2200 is actually just a, but it's slightly less expensive than the PIC alone.

MCP2200 The MCP2200 is actually a PIC 18F14K50 with a special firmware put into it. It requires the same sort of that a PIC does: • A reset pin is held high for normal operation with a 1K pull-up resistor (R6) • C1 is a decoupling capacitor (1uF) for the single MCP2200 supply pin • An internal 3.3volt regulator supplies the USB peripheral, it requires an external 470nF capacitor (C2) • A 12Mhz crystal(Y1) and two 27pF capacitor (C3,C4) provide the clock The chip is powered directly from the 5volt USB supply. Ferrite bead (L1) and 10uF capacitor (C5) filter the supply (not shown). LEDs LED connections LED Pin Indicates D1 GP6 USB RX D2 GP7 USB TX D3 GP0 /SUSPEND D4 GP1 CONFIG Four LEDs (D1-D4) are connected to the MCP2200 status indicator pins, as shown above. Each LED has a 1K current limiting resistor (R1-R4). PCB We used the freeware version of to make the schematic and PCB.
