HP 15c Collector's Edition save/restore does not work
Hello
Could anybody get this to work? I have a HP 15c_CE with new firmware (HP_IAR_USB 120ms.bin - checksum 0A0Ah - 2024-06-03) and the VoyagerSave.exe from https://hpcalcs.com/download. As mentioned in https://hpcalcs.com/downloads/apps/Voyag...ctions.pdf the calculator should go into HID mode after pressing [ON]/[f]&[ENTER] - and leave it with a hit on [ON]. Even this is not true for me. The calculator keeps only in the HID mode while I keep holding [f]&[ENTER]. When I release [f]&[ENTER] the calculator is switched on in normal operation and HID mode is off. I cannot imagine that the holding from [f]&[ENTER] is the "plan" to save and restore calculators memory. When I hold the calculator in HID mode with my left hand and key in with my right hand on the PC Code: VoyagerSave.exe -s memory I get a file memory with exactly 0 Bytes. Even this does not work. Does this work (and if how) for anybody? Fossy |

Hi,
It works for me. While the calculator is off, press [f]+[ENTER], hold them pressed, and then press and release [on] (nothing happens yet), THEN release [f]+[ENTER] and the calculator switches on in HID mode. The back-up file has always 2048 bytes - no matter the memory size mode we're in. If you do not get a permanent HID link then we have a problem...I'd reload the firmware and check that it is the same using the SAM-BA check button. |

My symptoms are slightly different. In Windows 11, I get a HID device called "HID-compliant vendor-defined device". When I run `VoyagerSave.exe -s filename`, it seems to hang there. I can Ctrl-C back to the CMD prompt, but no file has been created.
(I re-flashed the firmware and verified it just to make sure it was running the correct firmware, but it made no difference.) Then I tried it in a different USB port and it worked! The non-working USB device has a path like the following, and is a USB 2.0 port: Code: computer A working device in a USB 2.0 port has a path like the following: Code: computer It has one fewer levels of USB hubs than the non-working device. Here is another working device in a USB 3.0 port on the same XHCI controller: Code: computer Here is another working device in a USB 3.0 port on a different XHCI controller: Code: computer So it seems to be sensitive to the number of USB hubs in the chain, or at least the number of USB 2.0 hubs. — Ian Abbott |

Thanks ijabbott!
I had to change the USB-Port. Now it work's. For me it works with USB2 and USB3. It did not work with a long cable. But firmware flashing worked with the long cable. Fossy |
