where can i find software for this?

for Linux, you can refer libnfc, it includes various examples. As for device driver, you can download it here:http://www.acs.com.hk/download-driver-unified/5128/ACS-Unified-PKG-Lnx-112-P.zip

Can this be used to reset a Skylander or Amiibo toy?

I did not test those devices at ACR122U, However, if they support required tag specs, it could be, I think. Refer here: https://www.acs.com.hk/en/products/3/acr122u-usb-nfc-reader/; ACR122U supports ISO 14443 Type A and B cards, MIFARE, FeliCa, and all 4 types of NFC (ISO/IEC 18092) tags.
