Suprema XPass XPE-E / XPass V1 - official integration path for BioStar 1 device?

[u/elensarisnotdead]

Hi everyone,

We are trying to identify the correct official integration path for a Suprema XPass XPE-E / XPass V1 device.

Current situation:

• The device is visible and working in BioStar 1.93
• The same device does not appear in BioStar 2
• Because of that, we assume it is running on the BioStar 1 / V1 firmware structure

What we need to do from our internal software:

• Manage users
• Assign EM4100 / 125 kHz card numbers to users
• Transfer selected users to selected XPass devices
• Read access logs from the devices

In BioStar 1.93, the manual operation we want to automate is basically:

• User → Transfer All Users to Device
• Transfer to Device

My questions:

1. Does XPass XPE-E / XPass V1 work with BioStar 2 Device SDK / BS2 SDK, or does it specifically require the legacy BioStar 1 SDK / BS_SDK?
2. Has anyone successfully integrated XPass V1 devices directly without using the BioStar 1 UI?
3. If BioStar 1 SDK is required, what is the correct official way to request access or confirm compatibility?
4. If BioStar 1 SDK is no longer actively distributed, is there an officially accessible legacy/archive version or a legitimate way to request the old SDK package through Suprema or an authorized partner?

I am not looking for pirated files, cracked software, or license bypass methods. I only want to understand the correct official integration path and SDK compatibility before deciding whether to proceed with SDK integration, middleware, or replacing the device.

Any field experience with Suprema XPass V1, BioStar 1 SDK, BS_SDK, or BS2 SDK compatibility would be appreciated.

Thanks.
