no, thres at time only an very small assembler implementation to access usb hid devices as host. i have ported it to c for tests but have not managed it to get this working with other things (i wanted only to read the device descriptors).
i have found somebody who want to write his diplome work on implementing an sw host controller for small devices but its not finished and no word about avr

USB hosts must support at least Full Speed, that's 12 Mbit. Much too fast for a firmware-only implementation on the AVR.

In other words, it is unable to construct "software host for low-speed
devices" ?

A software host for low speed devices is possible and there are implementations available, see
