FemtoBolt serial number not correctly read by ROS driver after update to firmware 1.1.2

[bmegli]

With 1.0.9 firmware:

• driver correctly reads serial number of Femto Bolts

[12/19 10:40:27.701904][info][3412][DeviceManager.cpp:15] Current found device(s): (2)
[12/19 10:40:27.701911][info][3412][DeviceManager.cpp:24] 	- Name: Femto Bolt, PID: 0x066b, SN/ID: CL8R241010D, Connection: USB3.1

After upgrading Femto Bolt firmware to 1.1.2

• serial number is no longer correctly read by ROS driver

With Orbbec Viewer

• devices show also same "blank" SN/ID: CL000000000 in device list
• after selecting device it shows the true serial number so it is still there
  • just some mechanism of reading it is broken

---

Some side information:

• we needed to upgrade firmware at least to 1.1.0 to fix detection as USB 2.1 device
• but we also need serial number to identify multiple Femto Bolts connected to same machine

Also, if not trying to identify Femto by serial number

• ROS driver can read the serial number from device after connection
• which again confirms that
  • one of mechanisms of identyfing serial number used by ROS driver during initial connection is broken
