OK so far. PCI device id was recognized and hostap_pci stated initializing the card.

That's not good.. I haven't seen this with any PCI Prism2.5 card. linux-wlan-ng uses much larger delay in COR sreset for some reason, but it was not required on any of my cards. Anyway, you might try defining PRISM2_PCI_USE_LONG_DELAYS and retesting with this. Check driver/modules/hostap_pci.c for some info about this (prism2_pci_cor_sreset() function).

This is quite expected since COR sreset timed out and the card is in unknown state.

Isn't DWL-520 native PCI card based on Prism2.5? hostap_pci is the correct choice for it and hostap_cs will not work.

Have you upgraded firmware on the card? Have you tested with any other driver (i.e., does the card work at all anymore)?
