    * You can swap it from one unit to another (ex: swap from BP-1410 to BP-1600 to upgrade an old unit)

I analyzed the USB packet traces for kicks to see what was happening.  There are some minor differences (ex: later software chunks firmware load up smaller) but otherwise they are identical in purpose.  However, the newer software seems to just give up at one point.  My guess is that they removed the 1600 handling code, not just the parallel interface to it.

===== Phase 2: USB cap/replay =====
 
Continue above project by toying with USB driver.  Previously had some issue with certain response packet getting lost as it made its way back to the host (kernel capture: lost, libusb: lost, USB analyzer: received).  This issue is what prompted this more detailed analysis.  To that end, try to work in C to enable getting libusb help diagnosing the problem.

Rewire Saleae cleaner.  Confirmed that can select up to 500 MS/s with 2 channels with analog turned off

Background

At one point they sold an upgrade board to convert older programmers to USB. Basically what it boils down to is:

  • The adapter should work for BP-1400, BP-1600, BP-1700, and (some?) EPP series programmers
  • You can swap it from one unit to another (ex: swap from BP-1410 to BP-1600 to upgrade an old unit)
  • Units known to ship with this adapter
    • BP-1410 (probably BP-1610 and BP-1710 as well)
    • Silicon Sculptor 3
  • The adapter is no longer offered as an upgrade for the BP-1×00 models

[1]

Site USB 2.0 Adapter FAQ.doc

  • 2.4 Mb/s to 9.0 Mb/s potential speed upgradef
  • 14. What programming site models will this work with?
    • All EPP programmers. This encompasses 6th-gen and 7th-gen.
    • This may be a different adapter board
  • 17. About how much will these adapters cost to make?
    • About $20 in materials
  • 21. Why can’t I just buy an off-the-shelf USB-Parallel port adapter and use that?
    • There is no formal specification as to what you must do with these signals. Printer makers adhere to an informal standard as to what each of these signals does, but such functionality isn’t suitable for device programmers.
    • Even if the vendor-defined signals didn’t get in the way, the performance of any off-the-shelf adapter would be horrible (much worse than parallel port)
  • 20. What are the Macola part numbers of the site adapter and the hub?
    • Site Adapter: WWAVUSBEPP
    • Hub: WWAVUSBHUB

[2] 

 >> All I have is an Actel Silicon Sculptor 3, also made by BP Micro,

Other:

  • It's part number is WWAVUSBEPP

From another doc:

> Automated Programming System users can determine if the handler is configured with the USB to EPP adapter through the PC Device Manager. If “BP Microsystems SPC Interface” is present as shown in the object below, then the USB to EPP adapter is already installed. If not, please contact BPM Microsystems Sales to order an upgrade kit part number: WHARUSBSPCKIT.

Programmer compatibility

Trying a 1600 with the adapter under 5.33.0 (last version to support parallel) worked fine. However, under 5.47.0 (newest release version as of today):

I analyzed the USB packet traces for kicks to see what was happening. There are some minor differences (ex: later software chunks firmware load up smaller) but otherwise they are identical in purpose. However, the newer software seems to just give up at one point. My guess is that they removed the 1600 handling code, not just the parallel interface to it.

Original unit was from

Power to J4


CPCB12A Rev C motherboard (BP-1600, SS2)

Connect to TERM 1 (J11). TERM 2 (J12) will not work)

  • Most small capacitors. T13/T17 are recommended values from cypress datasheet
  • U3 is best guess
