Seems like I’m in trouble:
Today I received my assembled V328 and hooked it up right away…
I already had a slight feeling that the mini-USB connector was a bit on the loose side
(well, comparing it to my PSP, digital camera and a usb hub…)
and WinXP wouldn’t recognise it as a new device…
Then, somehow, the hardware wizard showed up and I could install all the needed drivers
and played a little with the blinking LED (onboard) examples of Arduino0017 software;
everything was fine till then…
Couple of hours later, after reattaching the USB cable, the ‘best’ thing that happened was
a USB symbol in the right bottom corner of the screen showing up and disappearing
again every couple of seconds. After doubleclicking on it I get a window saying
“USB device not recognised”
Upon opening the device manager (which then keeps automatically updating every ~3-4 seconds),
the only thing I can see is an “Unknown Device” among other usb devices,
which I am unable to (manually or automatically) install any of the ftdi drivers for.
The device manager now neither shows the previously installed COM-Port,
nor the ‘USB serial converter’ (well it does, if I set it to show hidden devices… )
I tried ‘wiggling’ the usb connector, thinking it could be the reason, but
then windows wouldn’t even show me that unknown device - as if
nothing was connected at all, so wiggling doesn’t help either…
I must say, the µC seems to be working fine, since the previously programmed
LED blinking loop works just fine.
The TX and RX LEDs blink twice, then remain off for ~2 seconds and then repeat it again.
I’ve tried using different USB ports, cables, another PC(notebook), external 9V battery,
but nothing seems to help
So, in short, it did work (fem usb plug seemed loose) and then it stopped, all other
parameters being same.
Any ideas what it can be?
Could the FTDI chip be fried? (but then again - how?)
thx in advance.
I’ve tried using FTDI’s program USB View and here’s what it says:
bMaxPacketSize0: 0x00 (0)
Current Config Value: 0x00
Device Bus Speed: Low
Device Address: 0x00
Open Pipes: 0
(I guess it’s the reason it doesn’t want to install any drivers)
