Abu Ḥātim mentioned him and said, “Trustworthy, exact.” (1)

ʿAbd Allah ibn Aḥmad transmitted from his father, who said: I once heard one of our companions relate that Yaḥyā ibn Maʿīn said, “ʿAbd al-Razzāq wrote me a letter of introduction to Hishām ibn Yūsuf, saying: ‘You are going to a man who—though the authorities may have altered him—has never altered his ḥadith.’”

Yaḥyā ibn Maʿīn also said, “We stayed at Hishām’s door for fifty days; he would not narrate a single ḥadith to us, and we would accompany him to the emir’s gate.”

Aḥmad ibn Ḥanbal said: I heard ʿAbd al-Razzāq remark, “He—meaning Yaḥyā ibn Maʿīn—came to him, so he slaughtered a sheep for him and extended every courtesy to him, doing this and that.” Aḥmad then added, “Hishām is too stingy to slaughter anything for him.”

Ibrāhīm ibn Yūsuf said: I heard Hishām ibn Yūsuf recount, “When Sufyān al-Thawrī came to Yemen he said, ‘Look for a scribe who writes quickly.’ They chose me, so I used to write for him.” (2)

Abū Zurʿa al-Rāzī said, “Hishām is the most accurate of the Yemenis in written transmission.” (3)

ʿAbd al-Razzāq said, “If the judge (i.e., Hishām) narrates to you, you have no need to write from anyone else.” (4)

I say: Hishām died in 197 AH, at some point in his seventies, as far as I can tell.
