so I've been reversing the classic mac os usb stack

and I found a credits easter egg of sorts.

The OHCI controller driver emulates a hub device, which uses the OHCI root hub registers on the back end.

The USB device string descriptors for this emulated hub have a list of credits on the end, starting from index 6:

The credits were removed at some point (the OHCI controller driver in Mac OS 9.2.2 has them all dummied out, replaced by a single ASCII space character), but the second part wasn't:

The USB standard device request GET_DESCRIPTOR also implements obtaining unknown descriptors of type 0x40. These return structures that after the standard two-byte descriptor header contain a 16-bit length followed by some data.

The data returned here are PICT-format images. The array used has space for 12 entries, but only 9 are used, and here they all are. (if it looks like less than 9 images are here, please view this post on the remote instance)
