Note: I had to enable initramfs

uhci_hcd 0000:00:1d.2: PCI INT C -> Link[LNKC] -> GSI 7 (level, low) -> IRQ 7
uhci_hcd 0000:00:1d.2: UHCI Host Controller
uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 4
uhci_hcd 0000:00:1d.2: irq 7, io base 0x0000f040
there are 4 of them, 2 of which use IRQ 11 and the last one IRQ 10.
The UHCI driver is selected in linux's configuration.
