Re: Driver for uConnect USB-serial adaptor?




It's not the MAX232 - the MAX232 (and variants) is a chip seen in practically every USB / serial interface, its sole purpose in these implementations is to convert/drive the 3v or 5v logic to RS232 (12v) levels. There is no driver glue associated with these chips usually, so it's either the CY7... or 89C... chip. If there's manufacturer names on the chips it is very likely you can search them in their respective website. The MAX232 I could identify since I've used it myself, and practically every RS232 interface uses it! The others I haven't come across.
Disassembling the MacOS9 driver might tell you one or two things - they may have left label info and string details which could allude to the chip types; also it could have info about the driver writers, whom you could check with (if you can trace them down) as to what the other chips are.

Hi,

The only other chip in there, other than the CY7C63001A-PC,
is marked as:

    89CN8ET
    MAX232N

A quick search on the internet shows that the relavent number
is the second one:

Would disassembling the driver for MacOS 9 tell me anything
useful? - note that this is not a speciality of mine.

Hi,
Do you know what chip your serial adaptor is using? If it's the PL2303 then you may be in luck - there's a driver for it (you need to alter its properties) and I'm working on another.

Hi,

I have just got an old uConnect USB-serial adaptor. I was hoping
to use this for by GPS devices, but none of the GPS clients seem
to see the USB dervice as a serial port. Follows is the details as
supplied by 'USB prober':

Low Speed device @ 6 (0x19134000):
.............................................. Vendor-specific device:
"uConnect"
Device Descriptor
Descriptor Version Number: 0x0100
Device Class: 255 (Vendor-specific)
Device Subclass: 1 (Vendor-specific)
Device Protocol: 0
Device MaxPacketSize: 8
Device VendorID/ProductID: 0x0741/0x0001 (unknown vendor)
Device Version Number: 0x0A00
Number of Configurations: 0
Manufacturer String: 18 "Momentum US Inc."
Product String: 52 "uConnect"
Serial Number String: 70 "April 27, 1999 10:00 AM"


 From opening up the box I see that the chip is labelled:

CY7C63001A-PC

Hopefully someone will be able to tell me whether there is a solution
to get this working, even if it having to modify some USB-serial
driver.

André-John
