Errors when trying to use a 16Mhz board

[ofek256]

D:\Docs\Arduino\libraries\TrinketHidCombo\usbdrv/asmcommon.inc: Assembler messages:
D:\Docs\Arduino\libraries\TrinketHidCombo\usbdrv/asmcommon.inc:98: Error: constant value required
D:\Docs\Arduino\libraries\TrinketHidCombo\usbdrv/asmcommon.inc:43: Error: invalid operands (ABS and UND sections) for <<' D:\Docs\Arduino\libraries\TrinketHidCombo\usbdrv/asmcommon.inc:59: Error: invalid operands (*ABS* and *UND* sections) for <<'
D:\Docs\Arduino\libraries\TrinketHidCombo\usbdrv/usbdrvasm16.inc:331: Error: invalid operands (ABS and UND sections) for `<<'
Compilation error: Error: 2 UNKNOWN: exit status 1

I get these errors when using a 16Mhz board (usbdrvasm16.inc from the official v-usb github). This doesn't happen on a 16.5Mhz board.

Any help solving these errors would be much appreciated.
Thanks!
