[chirp_users] UV-3R Troubleshooting

I just purchased some Baofeng UV-3R radios and am unable to connect to them
with chirp using OSX, so looking for some help with troubleshooting.

The error I get is the classic "Radio did not ACK first command".

I have chirp working just fine with other chinese radios including BF-F8HP,
BF-T1 and UV-9R.

The BF-F8HP / UV-5R cable I have, and the UV-3R cable both appear to use
the same Prolific chipset (the BF-T1 and UV-9R cables show up
differently)...

Under System Information / Hardware / USB:

*BFF8-HP / UV-5R cable (two-pin)*

USB-Serial Controller:

  Product ID: 0x2303
  Vendor ID: 0x067b  (Prolific Technology, Inc.)
  Version: 3.00
  Speed: Up to 12 Mb/s
  Manufacturer: Prolific Technology Inc.
  Location ID: 0x14100000 / 9
  Current Available (mA): 500
  Current Required (mA): 100
  Extra Operating Current (mA): 0

*UV-3R cable (single pin)*

USB-Serial Controller:

  Product ID: 0x2303
  Vendor ID: 0x067b  (Prolific Technology, Inc.)
  Version: 3.00
  Speed: Up to 12 Mb/s
  Manufacturer: Prolific Technology Inc.
  Location ID: 0x14100000 / 4
  Current Available (mA): 500
  Current Required (mA): 100
  Extra Operating Current (mA): 0

*BF-T1 cable (USB) & UV-9R (screw on pin connector)*
(Both show up identically under USB settings)

USB Serial:

  Product ID: 0x7523
  Vendor ID: 0x1a86
  Version: 2.64
  Speed: Up to 12 Mb/s
  Location ID: 0x14100000 / 12
  Current Available (mA): 500
  Current Required (mA): 98
  Extra Operating Current (mA): 0

>From what I've read possible issues could include a driver problem or
defective cable. But to my mind, given the chipset appears to be the same
and I have the BF-F8HP cable working, I would have thought that the UV-3R
cable would work as well?

Any ideas for how else to troubleshoot this? Is there anything that's worth
trying before I give up and order a different cable? (If not,
recommendations for a reliable source for a cable for the UV-3R would be
welcome.)

Thanks,
Matthew
